#PieFed just added a multi-reddit feature, which we're calling "Feeds". It combines multiple Communities (actors of type "Group" in ActivityPub) into one.

Feeds can be followed from other PieFed instances, which will subscribe the follower to all the communities in the feed.

Try it out at https://piefed.social/feeds

It's similar to PieFed's concept of a Topic https://piefed.social/topics, except topics are maintained by the instance admins. Feeds are crowdsourced and federated topics.
