It's indeed not a good one. Discord refined instant messaging and bolts other things on top like forums but isn't fundamentally different. Google Wave was (and still is) a completely different paradigm. Everything was natively collaborative: it mixed instant messaging with document edition (like Google Docs or pads) and any widget you could think of (polls, calendars, playing music, drawing, ...) could be added by users through sandboxed Javascript. The current closest I can think of is DeltaChat's webxdc.
I don’t get the downvotes. Discord for all its flaws is amazing. I never experienced wave so maybe the comparison is not a good one?
