Are you doing job interviews?

From Paul Graham in Hackers and Painters (a great book, by the way):

It seems surprising to me that any employer would be reluctant to let hackers work on open source projects. At Viaweb, we would have been reluctant to hire anyone who didn't. When we interviewed programmers, the main thing we cared about was what kind of software they wrote in their spare time. You can't do anything really well unless you love it, and if you love to hack you'll inevitably be working on projects of your own.
