I used to spend time at CastleCops. It got tough to stay there, though. For one thing, your starting page was "Your Favorites" and it became tough to find a way to get to the main forum index! Had to go somewhere else and then work your way back up. Next, CastleCops had to be one of the slowest servers on the Internet - and I'm not talking about when under DDOS attack - all the time for the last year or two.
The independent forums were great but a few of the private developer forums were pretty bad - I won't say which.
Thanks for the great news thread, as always, Ehtyar!
