I have been using discord for work these days, new gen workers are sort of prevalent there, and Slack is dying. I think they feel it’s more counterculture and cool. While I appreciate the move away from Slack, I wish someone brought IRC back. I cannot understand how people spend money on Discord, and a lot of it. There is so much personalization and fluff going on there as a monetized feature and the product is so full of ads that is insane to me.
