yeah i get those as well but that's really just a fear you need to step over, you won't get answers to those questions unless you try, i tend to try and at least participate even when i don't know anything and am only calling it cool or asking dumb basic questions (unless the topic does completely fly over my head), besides whatever your interests often seem to align with reemo's so you're fairly guaranteed to get a reply from him with the added bonus of others potentially being able to chime in and share their perspectives on the matter.
and as a sidenote, if anyone makes fun of others for making a genuine topic about something they are genuinely interested in, it won't go unpunished, in case such a fear is also present. not that this is something that happens but it doesn't hurt to make this statement preemptively, such behaviour does not belong here
