Believe it or not, I prefer #Nostr over #ATProto. At least, as the two protocols exist right now.
I don’t trust #Bluesky’s control over the firehose feed. It is expensive to set up a competitor, and even if you do, there’s no guarantee people using ATProto will use it.
Nostr’s relays are much cheaper and affordable. What’s more, a client can use multiple relays at once. If you want, you can even use a private Nostr relay.
