logic?

i was editing my side links and such and as i was studying my links to other people's blogs, i began to wonder what on earth my logic was in ordering them. i think i started out in alphabetical order by first name, then i started adding people's last names to the link. the alphabeticalness (yes i made that word up), was then lost. then instead of rearranging them by last name, i just left them by first name. except there are still some that are out of place.....
i guess that's what happened?
