Thank you! I have a list of other projects that are doing this. I'll add yours too; to me its the most complete so far.
I simply want a better way to do polls on Nostr; some way to vote, without spam on a note, no need to zap (at minimum) one single sat
I wanted an expiration to set a hard limit on the time to poll.
How awesome if you could add a way to determine POW for better anonymity & reduce spam.
