I knew there was a reason I hadn't written what seems to have become the obligatory first post of the New Year (because it invariably deals with resolutions, predictions, motivation, yadda yadda). That reason being I needed something really thoughtful to kick off 2010. And this post on measuring engagement aka relationships from - who else? - the queen of measurement, Katie Paine, is just that.

Thanks for starting off 2010 right, Katie.
