“local feed” on a smaller pixelfed instance will be smaller
“global feed” on every pixelfed instance will see all pixelfed and all (image) mastodon posts, but comments made on mastodon posts using pixelfed will not be seen on mastodon
in theory you can see Lemmy posts and subscribe to Lemmy communities with pixelfed but I haven’t got it to work. I’ve seen someone post from pixelfed to Lemmy but commenting didn’t really work.
does pixelfed not… uh… federate?
