Any lemmy community is federated to mastodon as a user. So you follow by addressing the community as you would on lemmy, but with an “@“ instead of a “!” at the beginning. So @learninglemmyandrust@lemmy.ml.

That “user” then boosts all posts and comments that occur in the community, which is generally annoying when there are piles of posts and comments. For this community though it probably makes a lot of sense and might be more useful at this size than what lemmy does.

Additionally, mastodon has lists which can be made exclusive so that items which go into a list do not show up in your home feed. So you could make one just for this community and check the list for any updates on anything that’s happening here. I might actually do this.

If you like, you can then post to the lemmy community from mastodon. See https://hachyderm.io/@maegul/110483509521476095 for a demo. Mainly useful if you want to connect communities on both platforms.
