The problem I have with Discord (as well as with IRC and Slack and other "chat" services) is insufficient structure to get a good overview of what's going on. Maybe it's not supposed to be used in a completionist way, but that makes me really uncomfortable. What if I miss something important!?!

It's even worse when a large part of the community is in a different time zone. I just come back every day with too big a pile of discussions and no way for me to make sense of what happened.

I understand the sentiment that I'm not supposed to read everything, but that's just not how I roll.

As a great example of a chat service that works well for me, take a look at Zulip. The UI takes some time of getting used to, but the way how all conversations are grouped into "topics" makes it so much easier to filter.

Discord threads could be used in a similar way, but they just never are. I blame it on the UI.
