Open-Source Spying - New York Times

Interesting reality check 

At first glance, the idea might seem slightly crazy. Outfit the C.I.A. and the F.B.I. with blogs and wikis?

There are many valuable blogs and wikis, of course, but they are vastly outnumbered by ones that exist to compile useless ephemera, celebrity gossip and flatly unverifiable assertions.
