I would occasionally pop into the LiveSound and AudioEngineering subreddits. Is there any interest in hosting those here? They seem to fit in with the theme of this server. Just a thought!
One thing I always found about reddit was that I never really absorbed who I was talking to or who was posting what. The user/OP takes a back-seat to the content, compared to the twitter/mastodon approach, where I always felt like I had a better idea who I was talking to - I guess because I'd chosen to follow those people.
