The #IndieWeb service #Bridgy is ready to handle bridge AT protocol and ActivityPub protocol posts and replies once federation is enabled in production (already working in sandbox test server).
The format will be:
To follow a #Fediverse account from BlueSky / AT protocol: <username>.<server_domain>.ap.brid.gy
To follow a BlueSky / AT protocol user: <username>@atproto.brid.gy
Example: @atp.youronly.one@atproto.brid.gy
This allows users from each side to see new posts and to reply to these threads.
What is more interesting is that, if you have IndieWeb support on your website or blog, you will see comments from BlueSky / AT protocol appear as a comment, thanks to #Webmention. It is already possible to do this with Fediverse / ActivityPub. ^_~
