Have you used the slack client with more than one server? Last time I did the whole UI would reload when you switched. Discord took off because: * The message search is much better than free tiers of slack * You don't need to set up a separate account per server * It didn't have the user limits of Teamspeak * It didn't have the ads of Skype * A big inflection point was Skype launching their desktop client that was basically Web Skype in a window and sucked * For a server with your gaming buddies, a drop in drop out perma voice channel is really a better model than distinct calls for slack. Also for public servers. And if you want to VC with your friends 1:1, the option is still there. * Link sharing to invite users to a server vs having to set up a server/bot to give out invites as running a public slack used to require. Also used to not even require an account so was great for that pick up player you found for one night * For the large server setups, discord's permission/moderation setup is way more flexible than Slack's. Slack basically has admin/not admin. (though discord does need to separate pinning from deleting other user's messages) --- For a summary, Slack is targeted at the business case. In a workplace chat, there should be no need to moderate, since bad behaviour can be taken to someone's boss/HR. And the sign up/multi server flow was not optimised for this usage model as Slack didn't care (at least when I last tried public Slacks, these days the only Slack I use is my employer's). Discord is actually optimised for consumer use cases, and consequently built up such a network effect that even if Slack did invest heavily in their UX there, would be quite behind.
