To me it seems easier to focus a group of users in one place than it is to spread discussions across multiple platforms.
We already have a YouTube channel with many user comments, we have the Steam forums where a lot of users comment and ask questions and we have the official IPACS forums here. We've also seen some subreddits pop up but only with very few users and there are probably also some Facebook groups.
For us as developers it is easiest to push out news and announcements here in this forum.
If you have the time to moderate a discord server, feel free to create one.
It could become a nice place to chat with other users or to organize group events or competitions, or to share your new user made content links.
For technical support we would like for you to redirect them to this forum or our support page at https://www.aerofly.com/support/ though. It's better if all support related questions can be answered in one place than spread across multiple different platforms.
Don't all rush at once!
