The problem arises when you have people that just now-and-then hop into the Discord. These people are not in the "clique" so they don't feel comfortable talking/discussing too much in the channels, and they also really have no clue where to go for any of the lost information these super users don't even think about. This is probably why I never really use Discord except for voice, since I just don't get anything at all from reading an endless chat log. It's like being someone stepping in to a tight knit friend group with a long history and no way of looking into it.
Discord will most likely have to figure out how they can keep it so that it works for these super users, but somehow make the information organized for people that aren't hard core community members.
Edit: Wrote "clique" wrong
