Before Valve and Gabe-mania my first dev crush was John Carmack. His postings and .plan files where were not only shockingly open and honest, but, I guess, genuine... it was apparent that here was a very successful man that was like me...an unrepentant nerd and geek! It is nice to know that that attribute of the company in general has not changed.
Every once in a great while I will get the feeling that I am the most productive coder on the planet. Then I remember Carmack's .plan files and am humbled.
