I was trying to provide a contrary opinion because I often see the HN hivemind hate on Discord heavily for no reason, while it's become a ubiquitous piece of software used by younger people that the older generations have been completely sleeping on and still think it's some niche version of IRC for gamers. Discord has hundreds of millions of users, it's a behemoth rivaling the big social networks.
As a random user, if I were trying to ask a question about this piece of software, I want to open the Discord server and ask it, I don't want to start researching whatever Zulip is and how to use it and figuring out how a new interface works
These might be good qualities for a gamer guild or YouTuber community, but it's a real barrier to participating in open source software communities.
Zulip is open, and doesn't have these restrictions (and already had many bridges and accessibility integrations). I participated in the Oil Zulip, and it was less of a hassle tHan to join a new Discord guild and navigating their adhoc rules bots.
Besides, how do you think a competing product should rise then?
