I've never worked in the valley, and honestly I feel no pressing urge to based on what I hear with regards to the bias in favour of twenty-somethings who can work 15+ hour days and live off of ramen.
I'm pushing into my mid-thirties this year, I'm married with two young children, and I simply can't work the kind of hours that I could ten years ago.
The thing is, I didn't do it then either, even when I could. I've always had the mentality that if I'm going to commit to your project, you're going to compensate me in cash or equity. It may also be why I'm happier in my career now that I contract than I ever was before. A days (genuinely hard) work for a days pay.
I simply never understood why someone would give so much of themselves for free in the pursuit of someone else's goals without a substantial slice of the pie. I still don't. And I suspect this is in large part why older developers are looked over (although maybe there's more to it).
Good job on the site, it certainly looks like its getting a lot of traction!
