In the conclusion: “Ultimately, it depends on what your goals are as a developer. If you’re aiming to reach a wide user base, Bluesky or Mastodon are your best bets. But maybe, like Rabble, you’d rather have complete control over your app’s destiny.”

The fact that bluesky and mastodon have more users right now seems temporary. I was more wondering about fundamental differences between BlueSky and Nostr at the protocol level. The article mentions BlueSky is more narrowly targeted for Twitter-like experiences and that the company behind it has big influence on the protocol (or just the data coming out of the current BlueSky client?).

I was hoping to find something like BlueSky protocol doesn’t have feature X that Nostr has, and you can’t just add feature X to the protocol because of Y.
