Mastodon is quite a bit bigger than Lemmy and if you make it easy to interact here some of the Mastodon users might decide to join Lemmy too. I’m kind of in the opposite situation, I’m on here and I don’t have a Mastodon, but if I could see more of Mastodon from Lemmy I might decide I’m interested enough in that content to make a Mastodon account. But I never really got into Twitter, even if some form of a character limit would help improve my writing.
