I’m not big on social media, so I hardly ever use Nostr, but this has been a great experience nevertheless; It’s amazing what the browser can handle, if you know how-to offload stuff.

If you want to know more, I’ve written about Nostr here: Hello Nostr. You might also want to checkout the “official” Nostr Website - there you’ll also find loads more clients, for every platform under the sun.
