I started using Mastodon a couple if years ago; didn’t stay for long but it definitely felt more…friendly than Reddit, or personal I suppose. Glad I found Lemmy though I love the message board/forum format way better than a Twitter like format that Mastodon seems to have, though I do like both
It was recommended to me over Reddit as well. As I said in another comment, I’ve dabbled with Mastodon as well but I think I may like Lemmy more
