A couple of years ago, I asked whether the world has too many blogs. My answer now, as it was then, is that if you think a huge number of people are hanging on your every word and can’t wait for you to publish whatever is on your mind, you’re likely deluding yourself.
On the other hand, if you realize that the old saw about “publish or perish” that was once true for professors has become true for most businesses, then you need to blog. Blogging will get you traffic. Traffic is good (read: long tail marketing).
