I've always been very busy (one of the main reasons I don't post on HN as much any more). I don't have a resume. I'm not on LinkedIn. If I ever ran low on work, it would probably take me a day or two and a few phone calls to find something.
I don't work on anything unless I find it incredibly compelling. I write applications. I've seen tons of different technologies, many old ones I still use. But I also get very jazzed learning new stuff and incorporating it into my toolbox.
I know tons of programmers in my age group. I'd classify them into 2 groups:
25% - just like me. You don't see our resumes because we're very happy building cool stuff and rarely look for work. We've also seen it all and can smell something we're not interested in a mile away. You don't see us at many events because we're so busy with work and life, we only pick the ones with the most promise of bang for the buck. Most of the programmers I know in this group would make phenomenal additions to many startups, but don't recognize this as a compelling alternative to what they're already doing. The best way to engage us is to seek us out, make friends, and share some stories about something cool you're working on.
75% - one year's experience 30 times, not 30 years experience. Unaware of modern technology. Couldn't write Hello World in anything other than BASIC, FORTRAN, or COBOL (and would probably misspell 50% of the words). No imagination. Limited ability to visualize the possibilities. Hiding under the radar in some enterprise. You don't want these people.
