Ran across an interesting blog post on MozSpeak.
I noticed Drupal now has a Piwik module. Some of the items on the TODO would probably be of interest to Piwik users in general (for example, a user tracking example is a frequently requested feature).
Before the new year, I moved all our web sites to Hostgator. Our former web server is now a glorified reverse proxy to our internal servers. Maybe it can host a public git or svn repository...
Other than the Dashboard, I think I prefer the left column navigation in this Flex-based Piwik client to the sticky superfish menu in Piwik. Something to think about, seeing as I wasn't able to migrate all the jquery UI plugins in my recent Piwik patch, and now that jQuery 1.3 is out (and a jquery UI release around the corner).
