VEVO tightens partnership with Facebook

Back in September, VEVO started to integrate videos and link accounts to Facebook, indicating an approach to Facebook and move away from Google's YouTube regarding. In January, VEVO had exploratory discussions with Facebook about migrating its video content over from YouTube. Now, VEVO's move to Facebook has become closer although the company is still not doing the whole jump as of yet. Starting March 9, VEVO users can log into the service using only Facebook, who have been notified via email (see here). Considering that VEVO draws approximately 90% of its traffic comes from YouTube, do you deem this move smart?
