One of the best reasons to blog is to achieve expert status in your field.  One blog that is always read by headhunters and their clients is the Marketing Headhunter blog.

He’s certainly seen as an expert in his field and with good reason.  His posts are relevant to his industry and they are almost always useful and informative.

I can only imagine the ROI on this blog, as it’s used to bring him employer clients AND employee clients.  If you’re looking for a good ‘example blog’, the Marketing Headhunter is a great one to watch.
