I have been seeing a lot of people that come into a question after the fact, and then use the comment section to answer the question. The only purpose of this is so their response appears at the top. I think this type of behavior needs to be discouraged, and the comment section only used for clarifying the questions.
Should we be flagging these comments, or is there a way to impact the people doing this?
And another thing, if someone write a comment as, "Community Wiki" that should be an automatic 50 point cost to the author. Then only people with a lot of rep would continue to be Wiki Politzi.
Update: Guess this is a sore topic. Anyway, why not just have a Community wiki "vote" button and be done with it?
