Back in the day, John Carmack would micro-blog on the finger protocol (<a href="http://en.wikipedia.org/wiki/Finger_protocol" rel="nofollow">http://en.wikipedia.org/wiki/Finger_protocol</a>). <i>finger johnc@idsoftware.com</i> got you Carmack's .plan file, a well-written and, for a time, frequently-updated journal of whatever programming challenges he happened to be facing at the time. <i>finger @idsoftware.com</i> got you the id corporate directory, a simple list of about 20 names and titles. The only titles were CEO, designer, and programmer. In a tech world awash, even then, with countless software engineers, senior software engineers, senior members of technical staff, architects, chief architects, CTOs, rock stars, and ninjas, it was always refreshing for me to see Carmack's humble programmer listing.<p>All of my heroes in the field are programmers.
