This is the kind of "sentiment" or background feeling that it's hard to point at examples of, but I'd say that the mods have been pretty evenhanded at keeping everybody on an even keel and reining in tempers.
I don't think they've been made to feel unwelcome, just that they've been asked to make substantive posts (I'd argue there are (still) fewer "I just signed in to say I like 4th ed. Bye!" posts than there are/were "I just signed in to say 4th ed ate my dog. Bye!" posts). This isn't because either position is unreasoned or anything, just that in the initial announcement, there was a tidal wave of nerd-rage; there are still a lot of healthy/normal members of the community who contribute here with negative points of view on 4th ed.
Everybody's been asked to make substantive posts. What's the point, otherwise?
