@snarfed.org@fed.brid.gy builds an AT bridge, similar to mostr.pub called blostr.pub . Now all bluesky users are available for communication with any fediverse instance that federates with blostr.pub(ie everyone except about half of the mastodon instances behind the rainbow curtain) and those same fediverse users are able to communicate with anyone on any bluesky/AT server(read: just bluesky) back. Is bluesky part of the fediverse?
