As today is an organization day, I was inspired to start by simplify categories for why.movie. There hasn't been a whole lot of functionality there because there were way too many and I was confusing categories with tags. Fortunately (thank joy) there was a lovely utility built in to WP to convert categories to tags. I've got categories down to 2 pages, which feels workable, I think was 3 or 4 when I started. The top level categories are 1.0 Story, 2.0 Production, 3.0 Infrastructure and 4.0 Moring Me. I think that establishes some cognitive easing and flow.
