The blog uses the same LUSH theme as in here, it's good looking, easy to customize and also for the sake of "one stone two birds".
Since I have used LUSH here the author quickly released a version for 1.5.2. Very nice of him but I still prefer not having any menu for themes as the additional codes actually interfere customization. I have in fact removed most of the menu driven codes for clarity.
I have also added a template for links, my del.icio.us and archives for this theme. These things are simply too long to go into sidebar.
After playing with more than 2 dozens of themes I now realize that a good theme design must have a good CSS sheet. Don't agree? A good CSS design gives you clean and neat codes for the theme files therefore making customization easy. That's my opinion anyway.
What left to do on LUSH may be
- A traditional search box on sidebar and a template for search result, live search don't get what you want all the time and in case some visitors are not used to it yet
- may be a 404 template, when no search results return currently I see a blank page
WP2.0.2 (download here) just released allegedly for security fixes. I'm still on 1.5.2 here a bit hesitated to upgrade until I hear no adverse comments.
