This question is being asked so much at the moment I decided to recreate the Where Was Dr. Neil web page. As the Virtual Earth team removed support for the older (less than 3 years old!) version of Virtual Earth, the old site was broken and I have not had the energy to repair it.
In the last month I received more than a dozen emails asking where I am, so I decided to rebuild the page using the new Virtual Earth Silverlight control. the Virtual Earth Silverlight control was announced (again for the third year) at Mix09 last month. It took less than a couple of hours yesterday evening to put this page together.
One of the things that I have always seen as very important is the ability to customize the experience with the map. I feel that, while the Silverlight Virtual Earth control lacks some of the functionality I might like to see in a full GIS system, it does provide a great new opportunity to build rich mapping experiences.
You can now track me again here.
