I'm OS agnostic, with a Linux preference. I've used them all, they all have issues, just pick the issues you are comfortable with 😂

Most people won't know about Nostr, just like they don't know about TCP/IP. To them it will just be an app, and the backend will be Nostr. How many people don't know Linux exists, but use software running on it every day? Most people using the internet I imagine.
