First, I think it's important for those of us that develop software to be learning about and writing "software on the side". Pursuing professional development outside of work hours is, I believe, the primary differentiator between real software developers and those that simply have a job programming.
The other meaning is that while software needs to be more than a job, it's also not life. Family and God come before career and software. Software needs to remain firmly "on the side".
My name is Mike Clement. I'm a husband, father of four and currently Principal Software Craftsman, Learning Coach and Co-founder at Greater Sum. I hope to provide something of value to the community and not just contribute to the echoes heard across the blogosphere.
