Web 2.0 Like taking a drink from a hosepipe?

I was chatting with a friend today about the mass of information we can access and share, and got into debate about how we can judge the authenticity of information now that conventional sources can be bypassed. He said that managing information in the Web 2.0 world was liking trying to take a drink from a hosepipe.

Well I stumbled on Life 2.0 and it pointed me to this great site popurls and it looks like a really neat way to avoid 'infochoke' (can I claim this folks!)
