Do you have 2 minutes to spare? That's what it takes to click on the link to one of the many Nostr web clients, generate a pair of nsec (private) and npub (public) keys, backup your nsec and start reading and posting notes. No need for any identification system, not username and password, no Głøøgł€ email address, no #BirdSite @tag, nuttin'!

Of course, if you happen not to have 2 minutes, you could also just click on the link of a client and start reading and posting notes. You can always backup your nsec later on, maybe another day in which you get something cancelled or rescheduled and you find yourself with nothing else to do for 90 seconds or so. :-)
