This can help a lot with adoption by “lame-sensitive” users. Snapchat’s confusing and unintuitive design kept “lame” parents, teachers, managers, etc off the platform and helped maintain a kind of exclusivity.

Discord still has that. Instagram is currently losing it. Skype once had it, but has long since lost it.

A platform that figures out how to be cool and stay cool will reap many benefits.

I'm not sure if I agree that's a valid disadvantage of using Discord though. The basic features of Discord are very easily to learn and you only come across the more complex features by needing to use them. I personally find IRC to be more complex to understand properly for a beginner. Being complex is anti-apple in terms of philosophy but I believe that it gives more usability in the long term.
