Peer to Patent, EFF style

An interesting twist on the "peer to patent" review idea: I've just seen the Electronic Frontier Foundation's patent-busting campaign, listing their top ten undesirable patents and inviting people to tell them about prior art so the patents can be busted. From the information on the website, it seems that they have had some success. A useful antidote to unjustified software and business methods patents? No doubt, though I always worry about the danger of mob rule - the difference between good patents and bad ones, which is subjective at the best of times, could easily be lost.
