it's not just here, or the topic. the on-line Forum format is in seriously decline - one could say near death. mobile devices, tweets, snapchat, etc. have taken over.
it's time came and has gone - altho my bet is,,, just as Facebook is now achieving has-been status, eventually the Forum format will resurge. the alternatives are just too clumsy.
I got involved with CompuServe Forums in the late '80's - I've watched the medium slow and now gasp for breath. some of the CompuServe forums have survived - moved to Forumania.com - but there are no new users - I recognize every name there from the 80's-90's-00's - when us old geezers are all dead, there will be no one there.
