I thought this was going to be a "what would you like to see in Web 3.0" discussion.
To hijack it in this direction, my suggestion is a 8u115h1t Filter. By clicking a radio button in Google 3.0, you can filter out all the 8u115h1t and pointless crap the web is clogged up with, and just find what you were looking for in the first place. :-D
