Social media by and for the people

Safety first

Basic safety features: mute, report, content warnings, and delete.

Scuttlebutt's "2 hops" algorithm restricts your view in most places to people you follow and the people they follow. This creates a safety net against spam and abuse that works similarly to social circles in the real world.

Instead of a single universal space, Nos helps create more scoped community focused social media.

"I'm not on Instagram.
I'm not on Facebook.
I'm not on Tik Tok and I never was.

Nostr to me seems like more than just another big media property, specifically because the idea that it's an unowned protocol. That to me is attractive, that's something I want to see succeed."

"This is my happy place."
