Are you seeing momentum shift to discord for very techie teams recently?
The free voice channels in Discord are great, and the admin controls with roles etc. but the community/userbase seems hard to develop paid apps for? Some of the popular bots are on millions of servers - but not sure how much revenue they do.
Slack's API still seems to have the edge with buttons and /slash commands.
what kind of income are top slack apps/bots generating?
most seem to be mostly appendages / bot APIs onto existing products, not standalone new bots, so it's a bit hard to judge.
