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)

Farcaster: crypto developers
Bluesky: Jack and his fans 
Mastodon: subculture enthusiasts
Lens: airdrop hunters

I understand. That summary is not entirely accurate. Personally, I feel that Bluesky does not have a distinct community culture. BTW, Jack has always been truly concerned about the development of Bluesky.

Literally everyone on Bluesky fucking hates Jack. Also he just has a board seat, nothing to do with the running of the company.
