In the words of University of Colorado law professor Paul Campos: 

I once asked a friend of mine, a novelist, why so many writers have drinking problems. "A better question is why so many drinkers have writing problems," he replied.

His response came to mind recently, when I began to toy with the idea of starting a blog. Although the contrarian in me is attracted to the prospect of being the last law professor in America without one, the advantages of the form are obvious.
