when I made my first follow pack on BlueSky it had only 4 Bitcoin devs that I could find on the platform.
you can start small and edit them as you find more people

I think a nice feature would be for the total number of users in a pack to be displayed next to the Follow All button, not just on the main list, so people know how many users they will be following before they add them.
Are contact lists backed up before adding a follow pack? An undo option (possibly using the backup) seems crucial
