Graffiti CMS Powered Blogs
So your interested in Graffiti CMS, but your not quite sure if it is for you. This tip is to give you an idea of who is using Graffiti CMS and what kind of sites they have created. This is not a comprehensive list, rather I tried to look for blogs and sites that used custom developed themes and a few of the standard themes as well.

This is also a good testimony of just how stable the Graffiti CMS version 1.0 release is for being such a new platform. I'm also very sorry if I overlooked your site, but feel free to post a link in the comments if you have a Graffiti CMS powered site you would like to share with the community.

Here are two more sites to add to your list.
http://ottoradke.com - custom theme that uses Blueprint CSS framework
http://itechnw.com - site that uses two themes, one for product content and another for the blog area
