Bing Wesmaster has had a radical makeover. The interface has been revamped using Microsoft Silverlight (well, someone has to use it I suppose, they've spent enough money on it) and it now has some really nice charting tools in there. The end result is much better than the previous version, although it still has fewer tools than Google Webmaster Tools and most of the sites have a 'no data available' message. Maybe it's going to take a little while for the new system to start collecting data from newly added sites.
