Some of us around here have been using Mastodon (aka Fedi) for a few years and are checking out Nostr to see what it's all about.
Sirs, if this is about the ownership of the meme from above I've seen it pushed by nostr:npub1gke42gwrz2ja5np9tpcr449785hx6zxgzf2329x8584h4d06puzqg33xp3. Otherwise I have no idea about what's the fedi thing. I use #nostr mostly.

I've tried Mastodon briefly some years ago and didn't enjoy it, not to mention the centralization aspect. Frankly, the zap feature on #nostr is a banger. It will be adopted by other platforms or they will go into oblivion.
I use Mastodon and Nostr equally and they each have their pros and cons but I only started using Nostr again recently because nostr:npub19ha7tju4teqp3dmwv4p28wrcy9zd6h6hxkg5mwvjrlfycweazpkse2q0fa and nostr:npub1yvscx9vrmpcmwcmydrm8lauqdpngum4ne8xmkgc2d4rcaxrx7tkswdwzdu were talking about checking it out on Bowl After Bowl to see if we could use it with what are already doing with Podcasting 2.0.
