I'll check out the Discord server because I want to see cool stuff other people are making, but I have no intention of seriously marketing my extension. I don't really want it to "take off" and become popular.

To me, FastStream is just a fun hobby project, not a product. I intend to always keep it free without unnecessary bloat or spyware of any kind. So, I don't really have a desire for it to be "successful" beyond it being immediately useful to me and a couple of my friends.
