Most of the legacy apps that became popular started off with a very restricted way to share text or media:

- twitter: 140 characters

- instagram: 1 photo at a time

- vine: short video recorded in app

- snapchat: short video, shared for short period of time

I could be wrong on some of these and maybe it's not important but i think people like the challenge of creating something in a limited space to show whats possible.

Any nostr apps like this?
