>>On the one hand, you have to know someone to know where to go, so it can be inaccessible in that way.

It's funny, this was kind of what made me bounce off of LJ back in the mid/late '00s. It mostly wasn't locked/private like a lot of Discord is (afaik, I'm not actually on Discord), but if you didn't know the active communities or active users, it was very hard to find fannish content via the search or tags functions.

Your thoughts on the ephemeral nature of Discord spaces are very interesting.
