Farcaster

zora, rodeo and interface all leverage public farcaster data to solve the cold start problem for their own private social networks, with their own follow & comment systems. 

Follows & comments in these apps aren't published back to farcaster.

is this a phase, or a broader indication of the long term incentives around apps leveraging social protocols just for GTM?

1. I think this is fine! Permissionless means you can build however you want.

2. For those that have been around for a while, Varun correctly predicted this and there was a lot of pushback from devs (remember amps?). Protocol follows only work if a large app like Warpcast is willing to follow that norm.

(To be clear again: these apps should build however they want and should not feel pressured to ask users for signers / add back to the graph if that's not beneficial to them.)
