I just heard that dan doesn't have a job... maybe it's time to make a big referral to join ahrefs
i know it’s pretty abstract which is partially a reflection of where i am in life (without a job and enjoying that atm) and partially because i inherently find these kinds of things interesting, which not everybody does. i know it’s not everyone’s cup of tea but i hope someone finds smt useful in it
