You can declare bounties, or donate to devs. There is no actual central project where to send it. Though you can always send to fiatjaf if you want, though he is also just one of the contributors.

Jack is not managing anything in nostr; he already gave the money to Fiatjaf, who is then going to 'drive' things from it. Its totally in his control now. And fiatjaf has contributed well for 2 yrs now to nostr.

Check out nostr console if you are handsy with keyboard and TUI (terminal user interface).

It has binaries for most desktop platforms. You can run it in docker. or in virutal machines, or build from code using Dart. Check out discussions and wiki sections for more info. I work on it mostly, so let me know any feedback.

hey, yes, I wrote #nostr client: https://github.com/vishalxl/nostr_console

Its a terminal based client. has binaries in release.

The simplest way to start using #nostr is to use the web app astral.ninja

If you have ios, there is an app Damus.

A list of clients is here: https://github.com/vishalxl/Nostr-Clients-Features-List

More than just a social network can be built on nostr. It gives you control of your own ideintity ( with public key/private key), so any reputation based system can be built on it, for example. Arcade City and Degen Rides are two p2p taxi services that are using #nostr too. for example.
