Plus there is some experience that you just can't get until you are part of bigger (i.e. "enterprise level") projects, and you've learned a lot of the "gotchas" that come along with that.
That's why, in part I'm spending some of my time in between job hunting working on contributing to an OS project, not because I'm going to be learning the latest django or javascript idiom so I can hit the ground running, or detailed algorithms for solving a complex problem, but because working with teams is a soft skill that takes time to develop. Also I use the project everyday.
