As communities are only federated with this instance when at least one of its users subscribes, new and small communities are at an inherent disadvantage in terms of discoverability. While not a problem unique to this instance, Lemmy Federate is used by several other instances to have a bot temporarily subscribe to communities from federated instances until at least one actual user from the instance subscribes.

Although the federation of additional communities means that users who curate their All feed via extensive community filter lists will have to filter more communities, I think the benefits to the discoverability of communities across Lemmy, promoting their growth in the process, would make it worthwhile.
