I agree. My experience with Discord vs. Slack is not nearly what people seem to make it out to be. I find Discord significantly more confusing and the concept of "servers" is not one that makes any actual sense; they are using that word as a stand-in for rooms/workspaces/etc, but "servers" sounds better to gamers. I can't blame them, but it's confusing to me. Oh well. I'm old.

I don't understand the point of your comment. How is it annoying that different interest groups are separated from each other? Reddit is split into different subredits, IRC is split into different servers and channels, forums do the same thing, I could go on. Would you rather everything be jumbled together in one place?

How is this any different than slack being split between workspaces?

It seems to me that the main organization model of Slack and Discord are the same.
