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?

Building FOSS via @frames, /open-frames to help decentralized social win. a16z CSX23. farcasterchannels.com farcaster.id

Apps can't fully use FC because they would need to gate on signup fees which is dumb. So they already need to manage their own social graph / follows.

Comments are only relevant in the context they are made. Not everyone uses FC. Sure you could cross-post for the people who want to, but wasted effort building this.
