Fred Giasson of the blog Fred On Something has developed a meta search engine for blogs that bundles results from Technorati, PubSub, BlogPulse, Bloglines, Ice Rocket, and Feedster onto one screen. That alone is useful, but the payoff of Talk Digger is a built-in tracker that remembers previous searches and graphs their trends. With this gadget in place, bloggers can quickly find new citations of individual blog entries. This thing makes it crystal clear how variable are the RSS engines in mthod and results. Unlike comparison engines that put Google and Yahoo! side by side, and usually generate results that both engines would recognize, Talk Digger results are all over the map. In any given search, one engine might report two citation; another hundreds.
