I agree with most of this. I've been coming here for quite awhile - visiting for years before becoming a member - and I have come to expect much more rational discussion here than any other site that I visit.
The mods do the yeoman work here, and I, for one, appreciate that they tend to hedge on the side of decency and sanity rather than allowing any and all comments. If you want an "anything goes" message board, there are more than enough venues for that. This board is generally a safe haven for enthusiasm, analysis, and insight without the overflow of negative commentary and emotional outbursts.
I do get frustrated when season-ending losses lead to a locked board for 24 hours or so, but a quick tour around other sites will remind you quickly why it is done.
Here's to hoping for no locked board this month, and a superior end to the season. We have so many reasons to be optimistic going into tournament time.
Go Duke!
