It never ceases to amaze me how many people give back to the community by plugins and of course themes, WordPress is blessed with a fantastic network of truly inspirational developers & designers.
Thanks for the post by the way!
It wold be interesting to see some research done on the theme of a site vs. CTR, user reviews etc. I am sure that the theme has an affect on the overall mood of a site and the end user experience, just not sure how much. I know when building and re-building my site I always try for friendly warm and cool colors, text that is easy to read and warm, etc.
