One of the many reasons why WordPress is such a super publishing platform are the many themes which are freely available to give your site a professional look and feel.
Envy is a bold and bright theme with plenty of different elements to help you personalise it.
Insense is a really classy, professional looking theme, which is just as useful for putting together a WP powered static site as it is a blog.
Perfect for photo or video based blogs.
Smart, darker theme. Sometimes themes with a black background can cause problems when inserting images – especially those with a transparent background. But Elite is still pretty smart looking.
Again, very professional looking, and the one I’ve used a few times in the past.
6. Bluvision – lucianmarin.com
A bit like Envy, in that it has lots of space for you to personalise your site’s appearance.
Nice, clean look – perfect for a personal blog.
8. Glossyblue – NDesign Studio
Glossyblue is a theme I used to use on LGNewMedia. It’s really rather lovely. I notice Tim Davies uses it for his Drupal-based blog.
9. Gridlock – Hyalineskies.com
Gridlock is a perfect theme for non-blog WordPress sites.
The theme I used for FEconnect, and I stil have a soft spot for it 
Dave: Thank you for featuring Envy at #1
