But Peter's observation is true nonetheless... it's quiet.

Video killed the radio star
Facebook killed the forum board culture.

I see it happening everywhere, not only in fandom but with all fora on all kinds of subjects and fields. And what's more, facebook has a lot less values and politeness than the boards have. Even in closed groups I see this. On social media many persons start behaving differently than they would otherwise, on- or offline. Which is a shame.
