But no one ever sees anything
I used to have 100s of comments and discussions ran on fir days

Have you looked into online community forums? Like phpbb (build your own, you’re the admin). Or Mybb. I believe they’re free. And there’s vBulletin.
They get as serious and thoughtful as you want them to be, and as far as I know, you’re not going to be monitored by anyone.
