Users on Mastodon can't really talk to users on Bluesky, both of which are increasingly popular alternatives to X. It wasn't possible before Bridgy Fed, anyway. This is a beta service that makes it possible for Bluesky and Fediverse-compatible applications, such as Mastodon, to interact.
The Great Twitter Exodus of 2022 is still happening. It's just a little...fractured. A lot of X power users migrated to Bluesky early on, which paved the way for a flood of folks to join that service in 2024. Meanwhile, a lot of technically inclined individuals are still hanging out on Mastodon (at least, that's where I hang out).
Bluesky and Mastodon are both decentralized services, in theory, but users of one service can't really talk to users on the other—or it wasn't possible before Bridgy Fed, anyway. It's a beta service that makes it possible for Bluesky and Fediverse-compatible applications, such as Mastodon, to interact.

This is where Bridgy Fed comes in. With this service, individual users of either service can opt in to "bridging" their accounts. I tested this out with my friend and Lifehacker alumni Eric Ravenscraft, who hangs out on Bluesky more than me. It worked well—we can now see each other's posts, like each other's posts, and even talk to each other, cross-network.

While this solution works well, there are a few hangups. Chiefly, it only functions if both people bridge their accounts. This means I can't see any comments from Bluesky users unless they also are bridged, and vice versa: During our little test, a few other Mastodon users responded to my conversation with Eric, but Eric could not see those replies. This make sense if you know how the system works—only comments from bridged users are bridged—but it's hardly ideal, and can lead to asymmetrical conversations. Unfortunately, the opt-in nature of the bridging service makes this inevitable.
If you are already using Bridgy Fed, how is it working out for you?
I've never been on Twitter/X, Bluesky, or Mastodon. But maybe I'd like to try.
So far I can't decide because I prefer Activity Pub in principle, but always felt FOMO with Twitter and don't want the same thing to happen with Bluesky.
I think the best of both worlds would be if I could make an account on both and have one account essentially repost anything from the main account, unless I'm replying to someone specifically where it wouldn't make sense to reply on both accounts.
Not sure if this bridge is a step in that direction, but it's far more important to me that everyone can see what I post on both sides than it is that people from both sides can reach me on a singular account. Not sure if others feel the same way.
I've been seeing people migrate in mass lately. The biggest issue with the above is that it's not at all intuitive. If Blue sky wants to be fediverse comparable, I think they need to make the process easier OR implement activity hub and link. As it is, all I see is people not opting in and a huge migration without activity hub users.
I've opted in on my fedi/mastodon account. But no one knows on the blue sky side to opt in so when I try to follow, no one shows up. It's easier to just follow on RSS.
Oh well we can still have fun on our side of the Internet.
I post on mastodon and bridge to bluesky. That way I can reach anyone there interested in following me, but I personally don't have to bother with the site at all.
As someone trying to reach an audience, it's pretty much perfect. Each to their own obviously.
