There's a class of interesting new applications known as "memetrackers". These apps use a variety of algorithms to identify, group and track memes. In this case as threads of conversation online. Examples include Gabe Rivera's Memeorandum, Kevin Burton's TailRank (for more on memetrackers see TechCrunch and Mashable).
Adam Green noticed that there's an ongoing discussion among some of the developers of these applications happening over at Battle of the Memetrackers. There's lots of interesting ideas and questions to be tackled in this space. Towards that end Adam suggested that a group blog be created as a forum for discussing these ideas and that possibly folks including Adam, myself, Dan Gillmore, and others might help coordinate.
As Adam notes: "Appropriately enough, the discussion of this idea will probably appear on the memetracker sites."
