Since Mastodon users communicate via Nostr to criticize Mastodon servers, it's obvious which platform is for communication and which one is not.

To your second point, non-crypto people don't want a social space full of crypto posts.

The "curate your own feed" concept fails in this area, since you cannot escape Bitcoin, Craig Wright, and "Look at how shitcoin dropped" posts that don't have tags or blocked key words in them.

I used to be all about Bitcoin until I joined Nostr. I'm still for it as a currency, but don't want to see valueless posts about it (or gloating over other crypto prices dropping, etc) anymore; and about 97.4% of Bitcoin related posts on Nostr have no value. Aside from some professional authors, it's sheer noise.

Non-cryptos will like Nostr as a social space once Nostr is not a cryto community. Until then, they will poke their head in, get bored by all the Bitcoin posts (and posts about Nostr) then leave; just like our metrics have shown for the last year.

Cheers to Mastodon users migrating to Nostr and bringing valued content with them.
