This is a great theme to start with a WordPress Blog. Ideal for beginners. It's simple and easy to customize. It looks decent but you would surely want to make some modifications of your own!
I have an old site I've needed to update my theme for, and WPStart did a great job right out of the box. I'll probably go in and modify it a bit, but I'm quite happy with it already.
I have been using WPstart as a starting point for most of the sites I own. Then I hack things around to give each site just a bit of a different look. Amazing theme. Highly recommended!
