Just have to chime in with my own anecdote that I find discord to be mostly bug free and an excellent, easy to use piece of software.

I can definitely agree with it being easy to use at least. I'd figure that's the main reason it's as popular as it is (together with the feature set, of course).

Being able to click a link and simply join a channel without all the fudging it can take when using TeamSpeak or even IRC is great, not to mention how easy it makes setting up your own "server".
