If anyone is interested, I’ve recently posted an article on how to get
Radiant working with Google’s Measure Map service (currently in alpha,
http://measuremap.com), at
http://codefluency.com/articles/2006/06/11/measure-map-with-radiant/
Once commenting becomes a built-in Radiant feature (meaning it will
support all the types of statistics tracking currently offered by the
Measure Map API), I’ll add the necessary information to the article
and will contact Google to have Radiant added to their list of
supported blog systems (as Typo is, currently).
