What are other people's impressions of the difference between the cultural vibe in farcaster vs bluesky vs mastodon vs lens?

(I have my own answers but am very curious what other people's answers are)

Obviously take with grain of salt

Nostr: Bitcoin maxis
Farcaster: Eth maxis but not degen
Lens: crypto maxis, yes degen
Bluesky: TPOT, generally left leaning
Mastodon: other Twitter refugees
Threads: people who missed the boat on becoming instafamous - a influencer power debt jubilee
