When I was in graduate school, the Russian historian Paul Bushkovitch once told me that the key to being a successful scholar was to become completely obsessed with a historical topic, to feel the urge to read and learn everything about an event, an era, or a person. In short, to become so knowledgeable and energetic about your subject matter that you become what others immediately recognize as a trusted, valuable expert.
As it turns out, blogs are perfect outlets for obsession. Now, there’s good and bad obsession. What the critics of blogs are worried about is the bad kind—the obsession that drives people to write about their breakfast in excruciating detail.
Yet, as Bushkovitch’s comment entailed, obsession—properly channeled and focused on a worthy subject—has its power. It forges experts. It stimulates a lifelong interest in learning (think, for a moment, about the countless examples of “retired” professors still writing influential books). The most stimulating, influential professors, even those with more traditional outlets for their work (like books and journals) overflow with views and thoughts. Shaped correctly, a blog can be a perfect place for that extra production of words and ideas.
