Build an MSDN-style content rater with ASP.NET, MS AJAX, and jQuery

In the MSDN library, content can be rated by clicking on a star (from 1 through 5). When you hover over the content rateR on MSDN2, a textbox appears to allow comments to be added. Using the rating control and the jQuery library, we can very easily create a content rater simliar to the one on MSDN.
