are there any comprehensive comparisons out there of farcaster vs lens protocol architecture? 

I'm more familiar with FC but would love to break down similarities & differences, could maybe even do it on a stream?

Another interesting one to compare with is sidetree - it’s not exactly social but has similar ideas to FC

identity.foundation/sidetree/spec/

Also interested in this. I learned about Lens a little back when the protocol was just released. But haven’t had the chance to explore FC yet
