Yes is decentralized like Mastodon. & a great place to be. I only joined out of curiosity. I'm glad I did.

I have two profiles each (different registration emails) on Mastodon and Bluesky.

My order of prefernce is Mastodon, Bluesky, and Twitter. Each has their pros ans cons versus the others.

Just know that Mastodon and Bluesky are not algorithm driven like Twitter. So, you only interact with users and tags that interest you.

On Mastodon, you choose who and what tags to follow even if they are on instances different from yours.

Even then, my Bluesky connections is growing relatively fast compared to my Twitter & Mastodon.
