AD: The prefix is my initials :) - my only HN account is a shared one with a co-op organisation I work through. I use AD to distinguish who's commenting... however my co-workers have yet to use this account ha!

AD: Pull requests are `patches` in radicle, when you clone a repository you create a git namespace for yourself from which you can edit to your hearts desire, you can then open patches to other repos via this mechanism.
