Jazz,
The only "problems" I've personally witnessed are:
1. situations such as the one I previously referenced where someone was pretty heavily reprimanded for using language / grammar / "off-color" humor in a post. Many moons ago no one would have blinked an eye at heavy sarcasm and using potty language; now people seem to get seriously upset if everyones "not taking it seriously" when they post. It often feels like we're in group therapy, not playtime.
2. If we want more traffic, then that's a problem. Because we don't have it. More traffic, I mean.
I think that's the stuff I've picked up from this thread, more or less. Of course, there's the ton of stuff that is great about the tfp, but I won't bother enumerating that. I think there's a thread on it somewhere
