Put Missing Kids on 404 Page – Entirely Client-Side with YQL, jQuery, and MSAjax (via Scott Hanselman)

I noticed a post over at a blog called “The
other side of the moon” where the author suggests that we put pictures and
details of missing children on on 404 pages. It’s a simple and brilliant idea.
Millions of 404s are delivered every day. We are reporting on missing
pages, but not on missing children. He includes a simple PHP solution.
I set out to create an ASP.NET solution, but then realized that a server-side
solution wasn’t really necessary.

Very nice idea, and implemented in seconds, although it’s only working for the US right now.
