(Disclaimer: I'm the person in the interview who blabbed on and on about how awesome open source is as a career move. ;))
This actually is far more an argument *for* working in an open source project than against.
When people think about the idea of using open source as a career launching pad, they generally think of two things:
- It's volunteer, which means you're not being paid. Ha! Sucker.
- It's IT, which is a dead-end in the U.S. due to shifts in the larger global markets. DANGER DANGER! SWITCH MAJORS NOW!
But that ignores entirely one of the biggest advantages of getting involved in an open source project with a large, thriving community such as Drupal: there are nearly limitless networking opportunities, and those can (and do) lead directly to careers.
Most of my first paid gigs as an independent consultant were from people I helped in the forums who needed some more "hands-on" assistance with their websites. The more people I helped, the more my reputation grew, and the more "human" connections I made. These connections, and the work I was doing out in the larger open source community, led directly to full-time employment with a Drupal shop. And this all happened within a matter of a couple months, mind you, not years.
Open source economies seem to exist independently of the larger global trends, from what I've experienced. It might very well be that if I tried to apply down the street at a local IT place, I'd be turned away. But within the Drupal community, at least, it certainly seems like we can't find people to fill positions fast enough. And with more and more companies depending on technologies like Linux, Subversion, Python, and Drupal, experience working directly on those tools with the very people who built them can only help your employment potential even at the local IT place, no?
