That could be the case! I do follow my lemmy-account from mastodon, (and the communities I mentioned as well).

This is a neat overview!! I like to federate my posts from microblogs as well, and did some tests.

Here are a few of my notes:

Viewing communities (from Mastodon) - that kind of depends? All communities I follow show up with their posts intact on mastodon (.social), but not when I use a different instance (e.g. mastodon.de) or software (examples: RenPy, Otome Games)

Viewing profiles (from Mastodon) - That also seems to depend on the instance. For example, here’s my profile as seen from mastodon.social. Viewing it from my Mastodon account, I can see all of the original posts and replies.
