Ability to relocate: Open to idea, can't right away That's why few were interested.
I can imagine that things like "Telecommuter?: Pretty please" and - as you mentioned - "Ability to relocate: Open to idea, can't right away" might've turned off a couple of the companies OP contacted.
What I would've liked to have seen was a more generally formulated and well-engineered resume that would've appealed to all but the most incompetent of HR decision makers, or even better, to A/B split test the email copy.
As such I don't think the post was as meaningful as made out to be.
