Yahoo’s Delicious adds a little Twitter

Delicious, the social-bookmarking service owned by Yahoo, has unveiled home page changes that are intended to do a better job of showcasing links that are currently popular. Although Delicious isn’t sharing the exact details of its algorithm, it apparently includes using the number of Twitter messages related to a given item.

Writing on the Delicious blog, Vik Singh, an architect at Yahoo, writes that “For this new Fresh homepage, our system displays recently bookmarked links and tweeted messages focused mostly on technology, web, politics, and media. Underneath the hood, Fresh factors several features into the ranking like related bookmark and tweet counts, “eats our own dogfood”  by leveraging BOSS to filter for high quality results, as well as stitches tweets to related articles even if the tweets do not provide matching URLs.”

The issue that Delicious is trying to address here is that the existing “Popular Bookmarks” tab (which will continue to be available) tends to point to what Singh describes as “authoritative resources rather than fresh news.” This is because, although Delicious is often described as a social-bookmarking service, in fact, many use it primarily as a way to store bookmarks online solely for their own purposes. And, in fact, Delicious even introduced private tags in 2007 that made it possible to save bookmarks without sharing.
