We’re naturally inclined to a technical solution here with a web application. No matter what, this will flummox some fraction of the population. Also, when dates open up, the ideal of “first-come, first-serve” degenerates into a game of chance based on who can get through. Given this, a solution would have been to get the Selective Service System involved and use something similar to the algorithm NIST came up with for the draft (obviously there would need to be separate async registration for that since everyone doesn’t have to register for the draft). There’s enough demand for this that people are willing to reschedule their life around their vax appointment, so choosing an appointment slot is unnecessary.
