API Update: Link Redirecting

Beginning on October 5th, some Delicious APIs will start returning URLs that redirect users through before reaching the final link. Most users will not notice this change, as all links stored on the Delicious website are already redirected through this same pathway.

There are two exceptions for which Delicious will still return the raw (original) URLs in the API response:

  • Requests for exported links
  • Requests for a user’s own personal links

Why is Delicious providing redirect URLs for API responses?
Delicious currently serves  2-3,000 RSS / API requests per second, and is committed to being a free and open service that is safe for all users.  Returning redirect URLs in the API response protects users by allowing Delicious to check all links against a list of spam websites and warn users before entering those sites.

What will redirect URL looks like?
To avoid returning redirect URLs with a lengthy number of characters, Delicious will use the link shortener

Who does this change impact?
This change may impact developers who have built applications that cluster links by domain based on the raw URL. Where possible, the API will return a new field, ‘expanded_url’ , that will contain the full URL, for users that explicitly need the unshortened URL.

An update to those users seeing spam in their saved links

Over the last few days, some users have reported that spam links have appeared amongst their saved links. We wanted to post a quick update with more information regarding this issue, and what we’re doing to get to the bottom of things. Here’s what you need to know:

  1. We believe the spam is posting to accounts through an HTTP API endpoint, as well as through, and seems to have impacted several thousand users by posting

    unsolicited links into their Delicious account.

  2. We have disabled some legacy API functionality, and are digging deeper into the root causes in order to enable some longer term solutions. Future versions of the Delicious API will be based on OAuth 2.0 and not legacy authentication methods – we will notify developers as newer API endpoints are available.
  3. We have temporarily disabled posting to Delicious accounts via email with to close a spam opening.
  4. Users who are seeing random spam amongst their saved links should delete those links. If the problem re-occurs or if there are more than a few please send a few sample URLs along with your username to so we can investigate further.

Apologies to those users who have been impacted; we will post again when we have more details to share.

Tweet a Link, Save a Link

Here at Delicious, we’re actively embracing the idea that the act of “bookmarking” has evolved beyond simply saving links.  By introducing stacks, we took the first step to transition content sharing on Delicious from a simple URL stream into sleek collections of your passions that include your own voice.

These days, great content is shared through a whole smorgasbord of social activities like retweeting and liking.  When you discover an interesting article or video and want to share

it with others, you’re most likely turning to a social media site like Twitter.  The need to share links quickly with tweeps while also capturing them for inclusion in a stack led us to our latest feature.

The new Twitter Connector on Delicious gives you the option of tethering your accounts together, so any link you tweet, retweet or favorite on Twitter is also saved to Delicious.  (Note to web speed junkies: sometimes the link-saving process can take a few minutes or more depending on system demands, so be patient!)

Here are some features and benefits of the Twitter Connector:

  • Every link you’ve shared via Twitter in the past (up to the last 3,200) will be imported into your Delicious account. (Delicious will ignore any duplicates)
  • You can choose a link-saving protocol for future tweets, including a) saving each link from Twitter going forward; b) saving just the links in tweets hashtagged with #d; c) saving every link except those hashtagged with #d.
  • You get to assign your own Delicious tag to every link coming from Twitter, and any hashtag included in your tweets (aside from #d) will be converted to unique tags on Delicious.
  • Multiple Twitter accounts can be set up, each with their own discreet settings and preferences.

Sharp-minded Delicious followers might recognize this as the same popular feature offered by, which we acquired last November.

This is just our first step in integrating Delicious with your current web habits.  We will soon offer features like automatically tweeting your activities and adding more social networks to further streamline link-saving and sharing with your friends.

Oh!  We should mention that the Twitter Connector will be gradually rolled out over the next week. To check whether it’s available to you, visit your account settings page. If you see a “Sources” tab, you’re golden.

Update on the browser extensions

In the past one of the ways of working with Delicious has been the browser extensions. For users of those extensions, it’s been frustrating that some of the features are not working.  There’s also inconsistency between the features in different browser extensions.  We want to clarify our position on the extensions and where we are going from here.

The original developers of the extensions did not anticipate Delicious users with thousands of bookmarks. As users noticed before the AVOS acquisition of Delicious, the extensions can at times transfer so much data that they cause problems with internet connections and browser stability. Rewriting the extensions to avoid these problems will take time and resources.

The challenge this creates is that our focus is on innovating and moving Delicious forward. We are rebuilding it into a site that once more attracts millions of people to enjoy the best content the web has to offer.  How the Delicious site works and operates is changing. It will continue to grow and change more quickly and this is where we are directing our efforts.

We recently reviewed the status of the extensions. Rather than keep people “hanging on” in the hope that we will work on them soon, we want to be up front about the following decisions we have reached:

  1. We’re putting the extensions on ice.  We will remove some broken options to avoid having non-functioning features deployed. This point is most relevant to the Firefox extension which always had more features than the others. Beyond this we have no current plans to continue developing them.
  2. We will promote the bookmarklet as the best way to interact with the site.  For the next few months this is where users will experience and see the changes we are bringing to Delicious.

If you already use a browser extension and are happy with it, then this has no impact on you.  If you want to experience the best that Delicious has to offer with the new features and changes we are launching, then we recommend that you use the bookmarklet.

We do believe extensions still have a place, but at the moment our priority is to focus resources on the experience at the front end of the site.  We’ll review the role extensions play with Delicious in several months time once the front end experience has further matured.

EDIT: Updated the link to reflect the new tools page location.

Chrome Browser issue that prevents bookmarking some sites with the bookmarklet

A small number of people have noticed problems when bookmarking sites like YouTube in the Chrome Browser with the Delicious Bookmarklet.  We’ve received confirmation that this issue is a problem with the latest release of Chrome when certain Chrome Applications are installed and also affects many other sites that have a JavaScript based bookmarklet.

When a Chrome Application like the Chrome YouTube Application is installed, it intercepts its URLs before the bookmarklet can see them causing the bookmarklet to fail.

The only work around we know at the moment is to delete the relevant Chrome Application (for example if you can’t bookmark YouTube links, make sure the YouTube Chrome App is removed).

This remains as an open bug with the Google Chrome development team, we’ll be sure to let you know if there is any change.

Minor enhancements and performance issues

We promised last week that upgrades will start to happen more frequently as we move onto the front foot with making Delicious the best place to discover and collect the web.

Site performance issues

As we’ve been introducing more features and Delicious starts growing again, underlying performance is increasingly becoming an issue.  We are currently working through caching issues in order to handle the high volume of RSS and API requests we receive daily.

We’ve made some changes which are helping, but there is still more to do.

We are also expanding our team to dedicate more operational resources on a 24×7 basis to ensure the site always performs at its best.  If you, or someone you know are interested, please refer to our jobs page.

Easier to browse and share stacks

Stacks are now even easier to browse, with Next and Previous buttons that hover as you scroll down the page allowing you to scan through stacks inside a category.  In addition to sharing via email, you can now share stacks directly to Twitter and Facebook.

In Summary

We’re not standing still, we continue to actively listen to and consider user feedback.  This latest release also includes many small visual and consistency tweaks in response to feedback, a fix to the Firefox Bookmarklet to get better consistency of tags and lots of other small improvements.

Over the next few weeks, we’ll be working on building ways of enabling you to work together on stacks, streamline

the stack experience, integrating more of the functionality from and continuing to improve and refine the overall experience on We’re also aware of an issue where YouTube Video pages can’t be saved in Chrome using the bookmarklet at the moment and we’re looking into it.

AVOS Acquires to Enhance Link-Saving in Delicious

San Mateo, CA – November 9, 2011 - AVOS Systems, which recently re-launched and is led by YouTube founders Chad Hurley and Steve Chen, has acquired link-saving service was founded in December 2010 by Tim Bull and Alex Dong, and is focused on making the bookmarking process more automated and supported by intuitive search. collects every link that users share or “like” on websites such as Twitter, Facebook and LinkedIn, and stores them in one place to make them easy to find.

“It became clear from the first discussion with’s founders that our visions for the future of bookmarking and discovery were closely aligned,” said Chad Hurley, CEO of AVOS. “Their technology and insights will accelerate link-saving and searching capabilities in Delicious.”

“We’re excited to join this stellar team and apply our bookmarking innovations to help Delicious users discover and collect the web,” said Tim Bull, co-founder of

More information on what this acquisition means for users can be found on their blog.

The First 20 Hours

It’s been quite a day. We launched the new Delicious a little before midnight last night, and it was amazing to watch new stacks being created and links being saved on our site just minutes later. Now it’s 20 hours later, and thousands of stacks have already been created. Thanks to everyone who gave stacks a try – please keep sending us feedback on what you think of the experience.

Speaking of feedback, we were thrilled to get so much of it today. Delicious is in “back to beta” mode, after all, and we’re depending on users to help us improve the interface and track down bugs. We spent a lot of time reading user emails and comments across Twitter, Facebook, YouTube, blogs and anywhere else we could think to look. All of it was helpful, and we responded to as many people as we could. For those who haven’t heard from us directly, hopefully this blog post will address your pending question or concern.

First and foremost, all previous Delicious users should know that if you agreed to transfer your data to AVOS, all that information is secure. If you’re not seeing all your bookmarks right now, it’s because we made a late decision to limit the amount of data we initially transferred from Yahoo!. We’ll be restoring all the data into your profile in the coming weeks. We should have made this limitation clearer to everyone from the outset, and I want to apologize for any headaches it has caused or will cause.

Beyond that, our engineers are drilling down on specific issues we’ve heard since the re-launch. We already completed these fixes:

  • RSS feeds working (fixed a DNS issue)
  • Fixed password reset process
  • Resolved bugs in feeds that were blocking link rolls

In addition, we’re working hard to address other issues that users mentioned today, including:

  • Fixing browser extensions in IE, Chrome and Firefox
  • Adding in tag bundle functionality
  • Increasing the number of links per page
  • …and many more

For the latest on the status of our features and functionality, your best bet will be to check the Delicious FAQ on our Help page, which will be updated regularly. We’ll also keep you updated on site progress through this blog and the Delicious Twitter feed and Facebook page.

This was an exciting first 20 hours for us, and there’s much more to come, so keep on saving and stacking those links!
