If you have a blog and nobody comments does it really exist?

I knew when I started this blog that I was doing this on my own to experiment and not to fill some untapped need for people clamoring to read my thoughts and ideas. However, not one comment? Not even by accident?
It does go to show that for a blog to be successful you need a following. Obvious, I know, but what does this mean for businesses who are being told to blog, blog, blog to drive traffic and generate leads but have very little brand recognition or following?
Blog it and they will come? Not so much.
