there's no fewer than 500,000 unique public keys, but probably a lot more.

This is the view from Iris, Im following the amythyst and damus relays too. Can one person have more than one key 🤷♂️. I know very little about no stir so education is welcome.
yes, there's no limit. you can make any number of keys.
Your IO thingy is really cool, I imagine if I lived in Stl I could follow you on the rss thing (in person), but Im so lazy that I just read my currated news from my google phone account. Idk what the Iris thing means, but if we explore it, iris will allow you me #[3] and pc users to build a common language to share with future avners to follow you into nostr 🤔
