I wouldn't go *that* far... :-)
We're still way better moderated, and way more under control than that zoo. I can't even stand to go there anymore. It really is totally *vile*.
I'll agree that the moderators do a great job here, but I do think that we've become a lot less civil and a lot more nasty.
We've still got a ways to go before becoming like DU, but we're definitely headed that way if folks don't learn to debate rather than attack.
That said, I have visited DU once. Once was enough.
