TODO
----

 * DELETE posts (since browsers don't delete, maybe a POST request to
   /k0s/20080302221048 might have to be used)

 * DELETE css files

 * edit posts TTW
 
 * User preference:  number of links to display in nav by default

 * How many posts to display by default at '/%(user)' ? 
   - there should be a preference for what to display by default (this
 month, this year, etc) and links to prev/next months for date views
   - there should (optionally) be a calender widget for easy navigation

 * it would be nice if the viewed user's blog was added to the site nav

 * middleware:
   - CSS zen garden (samadhi)
   - commenting
   - tagging
