You can post and do whatever you want

Welcome to the world of decentralized social communication. Why is it better? Because no one can stop you from participating, communicating, or building in what ever capacity you wish. You own your social graph and content. Welcome to Nostr 💜🫂🤙🏻

Mainly because it's far from just social media, it's the Internet with social connections - there's music, marketplaces, streaming, all sorts, all available with the use of your #nostr keypair, meaning your profile and follows are with you which ever service or platform you choose to use. There's loads of other cool stuff, but that's the big draw from my perspective
