Silverlight and web analytics

Thanks to Robert Basic, Germany's unofficial Problogger, I found a great video from the Mix07 conference in Vegas. The video contains one of the first applications made with Silverlight, developed by Avenue A/ Razorfish, one of my favorite NYC agencies. [flash][/flash]

After watching the video, I am wondering where web analytics is heading to. Current KPI's become more and more obsolete. I hope that web metrics god Eric Peterson and his efforts to measure the Web 2.0 are fast enough to keep up with the incredible fast speed of new web applications.
