Matt Asay: Red Hat - The mother of all open source business models
The biggest problem in open source today is that few now how to monetize it. There are great developers out there who will write free (as in freedom and price) software regardless of a profit motive, but they are the minority. These generous benefactors are not sufficient to fuel the continued rise of open source software.
So, we need more developers making more money to fuel...more development. But how? There are a few promising models (and the Open Source Business Conference is the best place to learn and develop new ones), and many more that are complete rubbish.
I'd like to focus on one, in particular, that I think is absolute genius: Red Hat's.
