Why in the world would I add additional work to my already busy schedule to have a Blog on my website? Well, the answer is that's were the action is today. What do I mean? the action is where people are going to learn about you (or me) and our products. They want up to date information, not last month's or last year's as many website demonstrate. The Blog allows you to keep the customer coming back to your site if you become the expert in your field in their eyes.
I would suggest putting a reminder in your Outlook or similar calender so you add to the Blog at least weekly. More as I become familiar with the medium.
