This is a quick follow-up to my last post about choosing a writing strategy for your for your blog. In the last post, I talked about treating your blog as an a forum to explore all the interesting things that you learn about through the web, reading, conversations, and all the other sources of information that come into your personal information universe. Readers will seek out your blog as a way of entering into your world and of finding resources that they never would have found on their own.

Another strategy is to pick out a particular area of expertise and write deeply and extensively about issues within that area. Readers come to your site because you know more about this topic than almost anyone else in the world. (Or at least on the internet.) The goal of this type of blogging is summed up in this quote from Ron Gross’s book The Independent Scholar’s Handbook:

Max Schuster was not a man to mince words or to warm you up with small talk. His words were well honed; he obviously had delivered this message before and knew exactly what he wanted to say and how he wanted to say it. Fixing me with a firm eye over the glistening mahogany desktop he declared: “I have one bit of advice for you–not just for success in this business, but personally. Begin at once–not today or tomorrow or at some indefinite date, but right now, at this precise moment–to chose some subject, some concept, some great name or idea or idea in history on which you can eventually make yourselves the world’s supreme expert. Start a crash program immediately to qualify yourself for this self-assignment through reading, research and reflection. In his librarylike office, such a program did not seem impossible, as a generous slice of the world’s wisdom was within arms reach.

In a world defined by the long tail, just about every topic needs its experts. One of my favorite examples has been

43 Folders where Merlin Mann has turned his own inability to manage his time and his life into what appears to be a full-time job. If you have a passion, no matter how narrow, your blog can be a place to find others who share it.
