Lemmy is not supported by any oligarch (afaik). Secondly, you can browse posts from other Lemmy instances! So.... people from Red-it: You came around before to have a look; don't you think it's time you settled in? A lot has improved since you visited the Fediverse; if you subscribe to feeds from other instances, when you click on 'Subscribed' or 'All' at the top, you just might see a similar amount of content that you saw on Rddt.
What I'm really hoping is that this instance really turns into an eye-opener for music and theory that I'm not familiar with. After all, there are so many genius-like musicians around the world, in history, etc. Wouldn't you like to learn about them?
