Younger/newer fans do tend to be a bit more volatile, though in the current situation in SGA fandom, I actually haven't noticed it making much difference; I've been through over a dozen fandoms and have had favorite characters on all points along the popularity continuum, but it hasn't stopped me from being extremely touchy about the current state of the fandom. *g*

But it's quite true that everyone has the right to vent on their own blog (and I'm totally cool with that), and we've all got to roll with it a little bit.
