Bluesky and Mastodon users can interact with each other (provided both parties opt in). I'm on Mastodon, but I see my friend's messages (he's on BlueSky) and vice versa. My replies show on up on BlueSky and vice versa.

I would love to see that work, but every time I've tried to set that up, it seems to fail. The bridges seem unreliable and non-responsive when trying to set them up or diagnose issues with them.
