I think its forums as a whole TBH, from how busy most were 4 years back its noting compaired to today for all forums, traffic is down, with teh likes of Facebbok as well anyone can create a page so people chat on that , you create a event people talk.
I have people on the Facebook page for my site they talk (rarely) but they never joined the forum again on Twitter i have bear on 700 followers and when i tweet something half decent i get 30 -40 re tweets and commenst but again none join the forum.
With Facebook you have non football mates games etc its all under the one roof.
Just my thoughts
