Bobbie Johnson in the Guardian's Technology supplement says Web 2.0 has given us all a voice, but suggests no-one is listening. Perhaps the start of a reassessment of social media - following on from Rich Skrenta's questioning of the success of news sites.
(Btw the same supplement suggests Snap Previews (which are enabled on here) are the most hated web 2.0 function. I rather like them. But if I'm alone in that I'll turn them off!)
