That's already super easy that an idiot like me hosts many of them. You can even do it straight from Umbrel these days with the cloudflare app if you want to get even simpler than what I use.

Very cool, I didn't know about that, thanks!
It'll be on my to-do for a simple guide soon!
I fully support everyone running one for their own community. That will likely be enough for 50% of the population. If you just want to speak to the people that are directly connected in your communities that's already nostr. The problem is building large enough relays that hold and distribute notes for even larger groups. if you want to reach those large audiences for whatever reason why not throw some sats to the big relays to be included on their billboard?
Guide sounds good!
