Joe Brockmeier has an
interesting piece up on the differences between paid and volunteer open source contributors. In it, he cites
this post from former
Debian Project Leader Martin Michlmayr, and a paper by Evangelia Berdou. Berdou finds that paid developers take up key positions in projects, while volunteers often work on the periphery. Kristin also had
some good? thoughts on the topic on OStatic this morning. I'm a believer that the combination of these two types of contributions can be very powerful.
