As a maintainer of a small open source project I have to disagree. The hurdle for someone to join Discord and ask a question is much lower than signing up to a custom forum and posting there. I also love interacting with people that use my stuff. Makes me feel warm and fuzzy to see that people are actually using it.
I can see the other side of course. There are a few things that are repeated questions or useful content that may benefit others. I try to push that stuff into GitHub or add it to the docs. I've also thought about recording the Discord channel and publishing that too, so that the search engines get it. I am afraid that that may scare people away though. If you feel like everything you ask (even with you pseudonym) is recorded forever, you are more afraid to ask stupid questions.
