You've got discord and a lot of other RP places to choose from too. I still manage to fill up on players within 24 hours any time I run a check, so I hesitate to use the word dead. Less active? Sure. Dead? Deffo nono.

Also I'm in my 30's and personally know several other people on the forum in my age group. We're out there but we aren't as numerous as the younger ones. Then again, who goes around on a forum waving their age around?
