Is it really necessary to connect to that many relays though? Why not just use the user defined relay list?
Discussion
As I understand it, Amethyst is using the "other" user's list of where they send notes to. This is allowing Amethyst to connect to the relays those users sent their notes to just like they fetch notes from where you defined to send notes to. I send my public notes to oxtr. Others fetch them from there.
Oh right, the outbox model
