I guess bridging with bluesky currently this does not make much sense to lemmy users?

As I understand it, Lemmy users do not have public messages, so no contextless posts like on Mastodon or Bluesky. On the other hand BridgyFed does not support communities, as a community cannot follow it.

So the way I have been using federation via ActivityHub, following communities and posting from mastodon, cannot be done from bluesky.
