Delicious Under AVOS Systems

After being purchased by AVOS Systems on Apr 27, 2011, Delicious went through significant UI redesigns and became more social.

On Sep 26, 2011, Delicious launched its completely new version 3.0 design in beta. Delicious added a new feature called Stacks that allows users to group multiple related links into a single page, and customize the Stack by adding a title, description, and a featured image.

On Dec 13, 2011, Delicious continued its work to redesign its site, including UI changes to the link-saving page and Stacks page. The new design, especially for the Stacks page, was similar to the design of another popular social photo-sharing website Pinterest.

On Jan 20, 2012, Delicious added more social features into its Stacks page, allowing users to collaborate on the same Stack, as a public Stack or a private Stack among a group of users. The users can also comment on a stack and create a stack as a response to the original stack. This new social feature was considered a good step against competitors such as Pinterest which did not offer private boards at the time.

On Mar 2, 2012, Delicious continued its effort to be more social, by providing a Twitter Connector that allows users to connect their Twitter accounts to their Delicious accounts. This new feature allowed tweeted links to be automatically saved into the Delicious account.

On Jul 20, 2012, Delicious reversed its position on the Stacks feature. All Stacks created by members were converted to tags in early Aug 2012, without any loss of member data. This was partly in response to AVOS's direction for Delicious and partly from feedback from Delicious members, many of whom felt that Stacks were trying to emulate features of the visual bookmarking site, Pinterest.


Delicious used a non-hierarchical classification system in which users could tag each of their bookmarks with freely chosen index terms (generating a kind of folksonomy). A combined view of everyone's bookmarks with a given tag was available; for instance, the URL displayed all of the most recent links tagged "wiki". Its collective nature made it possible to view bookmarks added by other users.

Delicious also allowed users to group links with similar topics together to form a "Stack", and include titles and descriptions for the Stack page. Stacks could be worked on collaboratively with other users and could be followed and shared with other users. Stacks were added in Sep 2011 and removed in Jul 2012.

Delicious had a "hotlist" on its home page and "recent" pages, which helped to make the website a conveyor of Internet memes and trends. Users could also explore stacks on the home page by navigating categories such as Arts & Design or Education.

Delicious was one of the most popular social bookmarking services. Many features contributed to this, including the website's simple interface, its human-readable URL scheme, a novel domain name, a simple REST-like API, and RSS feeds for web syndication.

Use of Delicious was free and a user could download his or her own data through the site's API in an XML or JSON format, or export it to a standard Netscape bookmarks format.

All bookmarks posted to Delicious were publicly viewable by default, although users could mark specific bookmarks as private, and imported bookmarks were private by default. The public aspect was emphasized; the site was not focused on storing private ("not shared") bookmark collections. Delicious link rolls, trolls, network badges, RSS feeds, and the site's daily blog posting feature could be used to display bookmarks on weblogs.


NameDomain name. (via

The "" domain name was a well-known example of a domain hack, an unconventional combination of letters to form a word or phrase.

In an interview, Schachter explained how he chose the name: "I'd registered the domain when .us opened the registry, and a quick test showed me the six letter suffixes that let me generate the most words. In early discussions, a friend referred to finding good links as 'eating cherries' and the metaphor stuck, I guess."

On Sep 6, 2007, Schachter announced the website's name would change to "Delicious" when the site would be redesigned. The new design went live on Jul 31, 2008. In Jan 2016, changes to the website were announced, including a move back to "".

On Apr 24, 2016, Delicious transitioned back to "".

Network Features

																	New features. (via

They weren’t kidding about a complete code rewrite. And while the point of the new version is to release something far more scalable and agile than the existing product, there are a number of new features. Most of them were highly requested by users. I’m still working through many of them.

There are a number of new sorting options. Instead of sorting bookmarks by how recent or popular they are, you can also sort alphabetically, and reverse sort any of the above. They have also added bulk tag editing (very much needed), and organization and sorting of your network of friends and people you watch.

The preview also includes a new search engine that includes contextual search. You can now search your own bookmarks, all bookmarks, or just your network’s bookmarks. If you do not specify what you want, it searches whatever you are currently looking at – your own bookmarks, bookmarks from your network, etc


																	Navigation. (via

The navigation bar is now organized into Bookmarks, People, and Tags. The tags section features a new MyTags page where you can see all of your tags in an expanded cloud. On the bar, you can search bookmarks amongst your own, networks, everyone’s, or the set you’re currently looking at.

Tag bar

The tag bar features tagging auto-complete and sorting alphabetically, by date, and popularity.


																	Bookmarks. (via

The bookmark summary can adjust the view detail, so you can either get more or less info with a single click. Also, the popularity of a bookmark can be determined quickly by the width and shade of the blue box around the save count. In addition to a complete history of everyone’s bookmarks for that web page, you can now see who in your network has saved the page.


																	Sidebar. (via

The sidebar lets you easily see a person’s list of top tags. You can also refine your view of bookmarks to specific categories as well. You can also give members in your network nicknames.

Action box

The action box provides you with a list of commonly used actions for the current page.
