This is not a race. As I said SN is SN with its own type of content and use case, nostr is nostr with other type of use case. Right now people are in a hype srage of using nostr as a replacement of twitter. But nostr is more than that, something that many people still do not realize.

I personally, prefer more SN to communicate, than nostr. I post sometimes on nostr (as social media) but I prefer to use nostr for other things than "social media".
