I don't understand how passion for programming/software dev/hacking in general means that its your only focus in the workplace or a signal that you should be taken advantage of. I'm passionate about programming because I am passionate about making stuff. I'm not very handy(carpentry, etc), so in this case a computer, editor and programming language scratches that itch. Contrary to the post I think that this is a fairly good indicator of how I am in the workplace and why I work for a (what a believe to be)cool startup. It gives me an opportunity to scratch this itch at work so when I am there it has my full effort/attention.
