Gunnar Peterson at 1Raindrop has created an excellent meme map for Web 2.0 security. Of course, his wicked security wit and humor is challenged considerably by the completely serious O’Reilly Web 2.0 meme map that was first out of the Web 2.0 blocks. Trust your users! Hackability! – good ones!
(I am actually pretty excited about Web 2.0 developments, but this complete ignorance of security is either hilarious or seriously depressing, depending on my mood…)
