Is it just me or are we about to see a new 5 cent an hour job crop up with 100,000 idian workers propping sites up. SEO 2.0 ..... Well if it ever comes to be that is.
I like the idea of banning sites from my personal search results but I think if they turn it into a social setting (reddit, digg) it will have a lot of potential to be a really bad idea.
