I couldn't help but notice that most (all?) of the projects he listed as good examples are open-source projects funded by companies. Magento, Firefox, Wordpress, PhoneGap; even jQTouch is maintained by an individual who does mobile consulting for a living. In this case, it's not a group of volunteers who are pitching in for a project, then someone putting together a website. The websites (and projects) in all of those cases are marketing a product that the creator of the website is making money off of (whether directly, though search revenue, consulting, etc).
