I have not seen thorkie much recently, but my forum activity has been down quite a bit. Last I saw of him he was posting on ODD74 and the ruins of murkhill forums. I just checked RoM and he was active earlier this month. He was active on DF around the same time as well. I have him on skype, so if I see him pop up sometime soon, I'll throw him a shout. I know he regularly takes breaks for forums.
I definitely see social media taking over forums place. I see facebook groups, G+ pages, and reddit as strong centers of discussion and forums slowly dwindling. 5e being so widely accepted certainly hurts the case for the OSR, as I know many OSR folks are happy to run 5e for a wider audience and just tweak it for their style.
