Here's a 5 minute tutorial that shows how to use Bing Maps and Photosynth. See it at http://youtu.be/DmQdRX91xUk

I appreciated the clear explanation on parts that might confuse people such as pointing out the different interface layouts for Bing Maps HTML and Bing Maps Silverlight and also pushpins being clustered until you zoom in closer.
