Can you give a bit more perspective, what do you find Discord confusing relative to? Because my comparison goes to IRC and Slack, and I find both of those far harder to use.

As it stands I can't say I see where you're coming from. It's a chat room, or really a series of chat rooms. If you have something to say or ask you find the appropriate channel and post a message there. If someone needs your attention specifically they'll @ you.

I'd say a chat room like this is strictly transient. Think "call", not "e-mail". Don't expect it to serve as an index of information, just treat it as more-or-less real-timely communication.
