My friend Vitek, who is not exactly MS technology fan 🙂 is working lately a lot of with Ruby, JavaScript and Google Maps API. If you are interested in any of those topics You might find his blog interesting.
Today he came out with idea to create iPhone like "throw scroll" experience for looking at Google Maps – interesting :). At least for me :). If you want to see it just go to Vitek's blog and test it on his test page.
