Iain Dale is entirely right to say that blogging is not really a number's game. He is right for all the reasons he mentions. The one area I would suggest adding to Dale's account is the blog as purely a personal thing- this blog is undisciplined and eclectic partly because it just contains what I'm interested in on a particular day, could be Roman history, could be a 21st century Iranian film. You can market your blog obviously by being more specific but I think it depends what you are aiming for whilst blogging. Iain has been, though coyly he doesn't say this quite, a very successful blogger partly for his chatty style. Others adopt different styles and personas but there is no one right way to blog, you blog because you want to and ultimately its an expression of your personality. A blog which was marketted to a specific degree and turned away from your personality would not be one that was enjoyable to write (I have sometimes written articles because I had to and often those are the worst articles on here in my opinion). Iain is absolutely right and in some ways the more we worry about audiences, the less like blogs we become, the more constrained we are by our audiences.
