Wild right.

Nostr is the "protocol" but not an App. It's just the set of rules all of this needs to follow to work together.

All the clients work differently. Amethyst, Damus, Snort.social, Nostrgram.

If you use a mobile phone app client remember to update it frequently as they're all essentially in testing or beta mode and being developed every day or so.

I just tried out a new Android cloet called Plebster. Not bad.
