Nostr microapp idea: You authorize the app the right to post on your behalf. when you see a post or a comment on Twitter that you like, you comment under it the words "Nostr this" and the post or comment above it gets posted in your Nostr account. Maybe it says "From Twitter" and has the username of who said the post, the username of who "Nostr'd" the post, and perhaps a direct link to the post.

Could make one for anything. Reddit, blah blah.

Oh, its how i imagine Twetch working (based on seeing people i disagree with write "Twetch dat", the world's ugliest sounding word, for the world's most evil community.
