I think there's opportunity for a Warpcast web chrome extension that offers some degree of customization for end user.

Not a client, not a frame, a secret third thing

I’ve often thought about the ability to “reply”
to any given website or page I’m on. An extension could show you that in a side panel. Or even comment on a particular line. 

See all of the conversation for a given news article or podcast episode for example. 

Casts as universal conversation for the Internet.

A social web annotation that enables you to comment and engage in discussions on any webpage - built on Farcaster.

This sounds like @buidler? Also just learned about it via @brianjckim under this cast lol
