There have been so many articles written about the perils, pitfalls, and possible rewards of running a business based on free or open source software that we can't possibly link to them all. Instead, let's ask MySQL
CEO Mårten Mickos
how to make money with a company based on free software, because he runs a company that is almost always touted as one of the world's greatest free software (business) successes. You may want to read some of these interviews
with Mårten before you come up with your own questions in order to avoid duplication, but other than that suggestion and the usual Slashdot interview rules
, ask whatever you like, however you like.
