TechCrunch is a recently launched blog dedicated to coverage of Web 2.0 applications. Edited by Michael Arrington and Keith Teare, TechCrunch is based out of Archimedes Ventures, a venture capital firm. Looks like they're essentially making a bit of their internal research visible to the outside world to garner mindshare and pick up bits of early feedback on emerging technologies. Interesting strategy.
As an example, they've gathered some initial data on Flock, apparently a Firefox mutant with social bookmarking and weblog editing baked in. From what I've seen so far, the TechCrunch team seems to have pretty good radar, so it's probably worth a webfeed subscription.
