Does the blogsphere suffer from "adverse blogger selection"? A tendency for those with real expertise in an area sit on the sidelines reading blogs but not writing since they are actually in the action... leaving only those with limited expertise to blog on a topic.
Does this theory help explain why the best blogs are often written by those in the analyst or venture capital community, where they are essentially marketing themselves and their services by demonstrating a strong understanding of various industries?
I have a strong feeling that "adverse blogger selection" is at work... and that the majority of blog readers haven't even thought about this issue.
