I mean, in order to talk about things you're doing, you actually have to post that you're doing them and what you think about them.
Obvs there's also the issue of not having other people into what you're into, but that's also been the Center for like 10 years now.
Only reason the Center's active is because it's old people yelling about kids these days (because the old people don't have time to actually do anything fun or explore anything new). Unless you play the same two video games that their wives give them 20 minutes of time to play every other week or mafia (a glorified sleepover game), there's not much happening there either.
