Two times I posted in the "Who wants to be hired?" HN thread in the past few years, I had a job within the month. Both times, I did not even have any resume or CV at all. But this year, I've been posting there for over 6 months and nothing. Not sure if attitude is such a big factor -- the job market kinda does what it does. You do make a mistake by not putting yourself out there though, because then there's basically no chance that an opportunity will come your way. One comment in an HN thread could be your ticket, or you could be applying to thousands of listings for months and getting nothing but the occasional rejection (though of course, never nearly as many as you made applications).
