@29decibel @christianselig There is actually, the activitypub protocol underlying Mastodon/Pixelfed is being extended to include groups, which is what Lemmy uses to power it's communities (subreddits). Lemmy communities are followable from Mastodon just like an account, and Bonfire, another activitypub-based project is also implementing groups aiming to be compatible with Lemmy, Mastodon, and other activitypub projects that support groups such as Guppe & Mobilizon.
