Accidentally found earlier today you can follow communities/magazines as “group”-tagged users in Mastodon, e.g. https://mastodon.social/@fediverse@lemmy.world
The problem is that posts in the community appear as boosts on Mastodon, and even replies are treated as posts. So if you follow a community with high engagement there, your feed easily gets flooded by replies people make to a given post.
Hope that helps _
Yeah, don’t do that.
You can follow PieFed users on Mastodon though - put the url of their profile into the search on Mastodon then click follow.
