Beauty is in the eye of the beholder; I guess. That site is not one I would considered technically worth much. It looks like it has not been touched in over a year (last blog post was Mar 2011). It has no flexibility, and is using an ancient doctype. It is just an old fashioned Wordpress template. Basically it looks like a million other sites, and I don't see that it has much to offer; and it is certainly not something you want to learn from.
