I've been building and designing software interfaces for two decades, and I think Discord's app has a shitty UX. Saying it is easy to use is a statement I find laughable at first, but it makes me wonder: compared to what? CLI apps?
>you need to reconsider your conceptions of what makes a great UX
Just because people are using a app without any real competitors doesn't mean that the UX is great. There is a lot of software that does its job well enough that people deal with the bad UI/UX.
Discord's UX is basically a slot machine from Vegas. Its obnoxious.
