I'm a huge fan of Techmeme, checking it several times a day to see what's being most discussed in the blogosphere and news sites. Now they've launched the Techmeme Leader Board which ranks sites based on the number of headline space they've gotten on Techmeme over the past 30 days. The Board is updated every 20 minutes.
Lots of discussion Monday when they launched. Of course as Michael Arrington said when he broke the story, The Technorati 100 is still alive and kicking, even though Dave Winer points out Technorati is "famously unreliable". But one thing worth noting is the fact that Technorati covers all types of blogs, while Techmeme is just tech-focused - they have separate sites for politics, gossip, and sports. They've also recently launched a mobile version so you can check out what's happening on your smartphone of choice. Robert Scoble called the Techmeme Board "the death of blogging" because he defines blogging as a single voice and many of those on the list are either aggregate blogs or news sites. I don't know about that. But I do know this is another great resource for all of us.
