FarCon

I heard a lot fear from builders at /farcon that Warpcast is unbeatable.

I agree - there are no large scale Twitter-clone client opportunities.

The client opportunities are in adding social to separate products: social onchain Robinhood, pump.fun with chat in channels, social context on transactions, etc.

any other current opportunity is just a feature that can be adopted by warpcast

I don't think those are opportunities, if they're just potential features of a twitter clone. Opportunities are a different type of client altogether. E.g. who's building something discord-like on Farcaster? Maybe leveraging the social graph but with private messages?
