In his talk, Joe reminded us of the #1 open source myth: Open source is comprised of mostly volunteers. The truth is, these days, pretty much any major open source project has people who are paid to work on it. There are always people who do it because they love it, but these days most of us are paid (and still love it). Over the years we have learned that if you want patches in a timely manner, you need people who are paid to do it.
