Stuff to build on Farcaster
Waitlist frame — make it easy to sign up for a product launch; send a direct cast then the product is launching or allowing batches of users off the waitlist
Airdrop to everyone in a thread action — for a given cast, extract the connected addresses on Ethereum or Solana for all replies engaged with by host, or simply everyone who liked the cast
Send a direct cast to everyone who liked a cast action
Follow everyone who replied to a cast and engaged with by the cast author, e.g. in an AMA
Follow Friday action — @alice starts a follow Friday cast and then anyone she is following can submit 3 people to follow; 1 click follow all of the recommended people (spammers won’t be followed by @alice so no need to worry about that)

Any time a cast >50 likes from people you follow, send as a direct cast
