Personally, if I see a software project on Discord, I nope out. I have made very few exceptions and every time I have come to the conclusion that it is not worth it. Discord isn’t really good for anything other than what it was designed for: Persistent IRC - plus a voice chat option. It’s perfectly fine to chat with a bunch of friends and play some games together. But that is about it.
It is terrible for tracking subjects, for finding information, for storing information, and for engaging in chats across more than one instance. It is unintuitive to navigate, and while they have made improvements, it is up to the user to make a server bearable to navigate by hiding the flood of channels that the average instance contains. Even so, Discord will still try to show you things you have explicitly disabled as a “suggestion”. Discord is bloody intolerable.
So yes, you may grow a community quickly because the people who already use Discord can jump on there. You will, however, lose a bunch of users wiling and able to use a better option who are, most likely, more experienced web users - and sick of the Discord bullshit. While this certainly includes me, I have seen the same sentiment again and again in my feeds. Power users tend to loathe Discord.
Discord is creepy if you examine the information they like to collect. On Android, for example, there are 11 unique data points. That’s not just an email.
