Changing The Unclean

I have been making several design changes to the unclean lately, and now am making some changes to the permalinks and site structure.
Normally, it's a very bad idea to make changes to urls and (less so) to the structure. In this case, however, the previous settings were doing more harm then making the changes will. I also have a graceful, and playful, method to redirect visitors. I also allow visitors to add pictures from some of the gallery albums to other websites, which will not be impacted by the adjustments.
Over the past 8 months I have studied and learned a lot about SEO and internet marketing in general. In fact, it has become my primary field of study for the past 6 months, and I have been able to make some tremendous gains. So, I felt it was time to make the changes needed to bring my favorite project up to speed. Funny thing, before I ever began studying SEO and internet marketing, I custom designed the header and did it damn good :);
Anyways, if you get a chance to swing by, let me know what you think of the current structure.
