Very late update: Bumped down so the more important stuff can float to the top.
Alright, we're nearing the end of the first weekend here and I've posted entirely too much about commenting. The posts were long(winded) and engendered some confusion/outrage elsewhere.
Here's the point about comments (being concise usually takes me three tries):
The usernames are so that we have people posting under consistent pseudonyms. This makes discussion better, easier, and more interactive. The asshole criterion was a misnomer. It's really a coward criterion. Don't exhibit cowardice in your comments and most comments will be approved. In the case some of yours aren't, you probably already have an idea of the reason for rejection. So, we aren't trying to stifle the asshole that resides inside all of us, be an asshole all you want in the comments, just do it with an OpenID.
I promise, that's it for ombudsing for a long, long while. The fun, hinted at here and here, starts anew tomorrow.
