I’ve been asked a billion times or so how one can make money with Open Source Software. My answers varied depending on who was actually asking the question, my mood at the time, and the availability of free time to go into details. But, as far as I can remember, I’ve always at least mentioned commercial support and customization.
But telling plain theory is a waste of time, unless good examples are given. And the examples have the tendency of getting outdated and forgotten pretty fast. So, it’s always good to refresh the stack of them.
One of the most recent ones that I’ve added to the list is WordPress. You can read all about it here. Hopefully, more information will be available later. I’d love to see the amounts of money, man-hours, and clients, as well as all the other details.
