I think the pie charts aren't just broken for document based technologies, they are wrong for anything where a user can have more than one of the tools. For example on our site we are using multiple types of advertising (including our own), multiple types of widgets, etc. That being said, very cool that you were able to pull this together - the raw data here is very neat and it would be cool if we could even dive in more and end users could play with it in different charts, etc.
