none of that makes it less usable. That side bar where its shown is mostly just to see who is online and I found for many users, they don't even have that bar showing. The core chat/voice/streaming is just as functional as ever.

It's actually not just as functional as ever. Quality of voice and video chat took a noticeable dive this year, maybe coincidentally right as vibe coding really took off in the industry. And all that extra crap might not make discord unusable but it does suck. Like I said, not great.

Animations from peoples' names and from their super reactions playing over other content after happening to move my mouse over them is something I'd consider a slight usability issue.
