I primarily use Twitter, but I added Bluesky, Threads, and Nostr (Primal) to give them all a shot.

Between Bluesky, Nostr, and Threads, Bluesky seems to be the winner. I believe the magic is in discoverability. The feeds system works quite well for finding new content and new people to connect with.

I know Nostr design is a focus on following specific people, but the onboarding experience is poor. A user shouldn't have to work so hard to find good content or they don't get hooked. Something needs to change.
