would be cool to implement a smol reactive lisp in grimoire so you can run scripts like:
;; Who do my friends follow that I don't?
(def friends-of-friends
(->> $contacts ; people I follow
(req :k 3 :a) ; their contact lists
(tags :p) ; who they follow
(diff $contacts) ; remove people I already follow
(diff #{$me}))) ; remove myself
;; See their recent posts
(req :k 1 :a friends-of-friends :l 50 :since 7d)
and get a custom feed. you can calculate rankings, pubkey sets, relay sets, etc. and the UI can show the right component for result. computed locally. shareable as nostr events.
