OpenStreetMap
Just wanted to express some joy over the super high quality aerials provided by Bing maps. Tracing buildings in great detail has now become very simple, albeit somewhat slow due to my perfectionism. But I trace in two different modes, to get some quick rewards once in a while: really detailed or just really quickly drawn building outlines.
In general, buildings are a lot of fun. Lots of tracing, less thinking, and a very visible result.

I have to agree with you. I find that the accuracy of my traced buildings is better than 3 ft throughout (actually more like 2 ft or better, but I am very conservative when making such claims), as judged by underlays of other aerial images in Potlatch2 and cross-referencing roadways.

I am glad someone have joy over the Bing photos. In my area it seems GeoEye skipped the ortification and we are left with wild inaccuracies that render the photos unusable :(
