I've been finding quality of posts and discourse on Farcaster consistently high recently. My impression is that it got spammy around 6 months ago, but since then has quietly improved a lotl

I notice waves of bots, but they get dealt with rather rapidly.  The meta discourse here has been fascinating, and the rapid development that's been recently spurred is particularly cool.  I think some of it is related to Moxie - it increased farmers and spammers, yes, but it's also spurring actual dedicated users to deeper engagement as they seek to find other dedicated users through the noise.
