A renaissance man in a culture of specialization.

I have been thinking a lot lately about the direction that I want to go with squeezed fresh. Oh, I know all of the sound advice that various experts across the web offer. If you want to gain any real following, you need to become an expert in an area. You need to be on topic and consistent with all of your posts. You need to post regularly placed, useful posts in your area of expertise. I know all of that. And the infuriating thing for me is that it is all sound advice. I know that I need to settle into the type of blog I am running. Am I a self improvement blog, a political blog, or a music blog? The obvious answer would be to just pick what you are most passionate about and stick with it.
Therein of course lies the problem for me. I am not jesting in the least when I tell you that I am PASSIONATELY INTERESTED in everything. I love music, and politics, and self improvement, and photography, and technology, and culture trends, and outdoor sports, and the arts, and spirituality. If I were to blog on what I was passionate about, I would blog on everything. I am a jack of all trades in a sea of specialists. According to princeton word net I am a renaissance man:

"Renaissance man, generalist; a modern scholar who is in a position to acquire more than superficial knowledge about many different interests"

This is so true of me. And I love being me. I love learning for the sake of learning. I thrive on new experience. But is there a place for a person like myself in a culture that prizes specialization? Am I doomed to a 10-hit-a-day blog if I focus on being a modern renaissance man? Or, on a more positive note, will the long tail have grown so long that I can connect with hundreds of thousands of other individuals like myself? The reward of connecting with other renaissance people everywhere would be beyond value to me. Who knows, perhaps I could be the progenitor of a new movement of learning and thinking outside of our specialties! But enough dreaming. For now, I have a choice to make. either pick a blog specialty and stick with it, or chronicle my passion for passions, even if nobody listens. Any advice you, o reader, can offer me would be most welcome.
