I haven't heard or read anything about it, but I just performed a google search and I was shocked to see three new little icons next to each search result.

One of them says "promote" which I guess adds to its credibility, another says "remove" which I guess flags a page as being no good, and the third says "comment" and when clicked pops open a text entry box for you to add a comment.

Anyone know anything about this business?

Whoa...
