I think it also helps me to understand partly why my blog has never managed to go anywhere. Sure, I've written almost 600 posts and gained some valuable experience, but my readership never took off. I think the reason why is because this blog has always been about me. That's fine, because it's my blog. But then again, who are "we" in the context of my blog? What community could I write for?
I better figure that out. In the meantime, read Chris' awesome post.
