Atlas Mashup Contest - We have a winner!
Alessandro Gallo, better known in the Atlas (sorry AJAX Library/Extensions) community as Garbin, has justifiably won the mashup contest hosted over on the ASP.NET Atlas site.
Garbin is a really smart guy who knows a hell of a lot about Atlas/AJAX Library and is a recent contributor to the Atlas control toolkit. He is also a regular contributor and part runner (I think?) of the DotNetSlackers site which is where the mashup is hosted.
I encourage you to check out hisGeoTagIt!! application. He provides full source code as well.
