I found Lemmy because I learned I could crosspost my relevant Mastodon posts to a Lemmy community. That's an easier way to get more posts, because I can get engagement from either Mastodon or Lemmy and it doesn't feel like I'm posting on a dead forum just to be forgotten about. Also I find myself checking up on that Lemmy community directly to see what other people are posting, because viewing the content from Mastodon is too messy.
