Discord's Recent Announcement made a lot of people mad, mostly because of Hyrum's Law - users were relying on unintended observable behavior in the original username system, and are mad that their use-cases are being broken despite very good evidence that the current system is problematic. I think the major issue here is that Discord didn't go far enough, and as a result, it's confusing users who are unaware of the technical and practical reasons for the username change, or what a username is even for.
TL;DR usernames in the new system are more like friend codes than usernames; Discord should treat them as such
icq needed no usernames! We walked up hill both ways to the internet
I still know my id…I haven’t used icq in well over a decade.
dang, I forgot my icq but I was proud af since my icq number is really low, most of my friends at the time have one or more digits than I was.
Yeah, we used to have proper phone numbers and we had to remember those on a snow storm!
