These centralized sites makes it easier to stick around. That forum I signed up for in 2012? I don’t remember the name. That Facebook group I joined in 2012?

These centralized sites makes it easier to stick around. That forum I signed up for in 2012? I don’t remember the name. That Facebook group I joined in 2012? I still see the occasional post in the feed. Also it’s vastly easier to find these communities in the first place. There’s no way to look for forums about a specific topic, if that exists at all.
