I think because many 3e people were unhappy about the change-over, criticizing 4e was a real dry thatch plus match issue. So I will put forward that I feel, for a time, pro-3e, critical of 4e people had to endure a certain level of stifling. When I say stifling, I mean only that certain lines of conversation were not as free, not that I think any person was ill-treated. I remember the moderation being fair, even patient. It is unfortunate that 3e fans were not able to be as vocal as they might like, but I do not think that was caused by the moderators or even necessarily by anti-3e posters. Rather, I think it was a function of the context (edition changeover), the politeness level this board calibrates for, and the topic flammability.
While it is not possible to be rude to a game, frank discussion is more likely to cross the lines of politeness, as experienced by any given person. So I can see what frankthedm is saying, to an extent. But I think 4e can be criticized strongly but in a fashion that is respectful to other posters, and I have faith in the moderation team to respond fairly to people posting in good faith.
I am pleasantly surprised at how quickly the boards have returned to normalcy.
