I'd been seeing posts in the new queue which are lighter colored text than others, and wasn't sure what that was - well, now I know. It's a damned clever way of showing edits! The more you edit a post the lighter it fades..
Actually, I wanna see how far that goes. I'll add a few edits to this post over time, maybe I can make it disappear. That won't hurt my reputation or anything will it?
