It's a comment-voting system. After careful consideration, it was decided that people should be allowed to have a "no" vote as well as a "yes" vote. We've been told how important it is to have the ability for people to vote no as well as yes. It takes a lot of no-votes to start the text fading out, but it can still be easily read by highlighting the text.

My own point is that none of this is available now, so there's apparently nothing to gain by flagging an account, until those other features are finished. There's no bonus to respectability, it doesn't affect traffic or search, etc. So, why hustle the flagging out the door, before any of the rest of it is ready for testing?
