For me personally, I stopped playing RS a lot, spent another year or so playing in bursts and then stopped playing completely. Even after I stopped playing completely I stayed around on various community sites/irc and kept up with a couple of youtube channels etc. but that dropped off over time and nowadays I just have sporadic contact with the closer friends I made from RS.
The game feels completely alien even from when I used to enjoy playing, which wasn't so long ago... and I won't be playing RS3 again. For those of us who did mostly use TIF for the RS related side of things rather than off topic, once you stop playing you obviously check the site less and less and get out of the habit of doing so. I'd guess it's mostly the OT guys who are still around now?
I don't see reddit as a replacement for forums, I use both mediums differently and very, very rarely contribute anything myself on reddit. But I can see how people would focus more on subreddits than community sites nowadays.
