When people will search for you online, you'd rather have them land on your blog, no? This is a great opportunity to market yourself. You don't have to blog to build an audience..
And it's not that hard, especially if you don't have a famous or extremely common name. I got to the top Google search result for my name in less than 3 months.
Another tip for accomplishing the same thing: being active on mailing lists and having a .signature with a link to your site. Open source projects are a great way to build up google points.
