"The majority of the work on this release has been on our ranking algorithms. Tailrank now breaks stories faster, cluster them better, and generally does a better job at finding the hottest news in the blogosphere."
The new Tailrank also enables a user to track each story via RSS or by AOL Instant Messenger. This could be a helpful feature with stories that get a lot of coverage and are worth tracking via IM alerts. Tailrank also introduced archives for the most popular stories of the week which could come in very handy if you miss a day or two of news. In addition to the algorithmic changes and story tracking features Tailrank is looking to expand to add new categories, like entertainment, with more to come soon. Finally, Tailrank hints at a number of new features within the next couple of weeks. It will be interesting to see what Tailrank 2.1 will bring.
Bottom-line: The new Tailrank looks much improved and will probably give Gabe Rivera's Techmeme some solid competition.
