dave is not correct here, to my knowledge Damus does not display a feed of current new profiles. Neither does Astral if it does something at all at the moment. Nostr Console might at least dispay the raw data - not very comfortable and also requires a download/build.

Of course it would be no rocket science to integrate such a feature, as profiles are just kind 0 notes posted to the relays.

If you check https://nostrdebug.com/query?base64=eyJraW5kcyI6WzBdLCJzaW5jZSI6MTcyNTAwMTIwMCwidW50aWwiOjE3MjUwMTkyMDB9

There is a profile stored every few minutes. To decide if it is new is not that easy as relays may drop older versions of the profile quickly. So a client had to check for any published profile event if there is an older event or the client has seen this account before.
