Besides, how do you think a competing product should rise then?
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.
As a sidenote: is the windmill hub open-source too? Does it make use of the base product to operate? I think it might be a good candidate for showing what your product is capable of, as an actual example of use in production
One nitpick: In my humble opinon, you should switch from Discord chat to Zulip.
It's completely open-source (Apache 2, self-hostable, free full cloud plan for open-source projects) and has an excellent threads-first (called "topics" model): https://zulip.com/why-zulip/
It can run fully in the browser, but it has desktop and mobile clients as well.
It also supports public channels which AFAIK discord doesn't. So you can link to specific messages inside a GitHub issue and anyone who doesn't even have an account can see the relevant messages and context.
Interestingly it's what the Rust language team (and community) uses for comms: https://rust-lang.zulipchat.com
(I'm not affiliated in any way with Zulip btw, I just love the product)
