User blog default

I'm working on setting up MySite as a personalized presentation site - in other words, as a home page that users would show to others, rather than one they'd use themselves. (I saw that there was already some discussion on using MySite for this) As such, I'd like to be able to give them a default layout where each user's own blog was already presented. At current, it doesn't seem possible to select the user's own blog in the default content, only a specific blog.
