Interested in US Elections '08 ? Check out this cool site from MSN, The Podium '08 - Election Guide 2008. This is built using Silverlight1.0 which gives a rich UI and seamlessly integrates Live Search.
Actually when you click on a candidate and want to know his/her view on a particular issue, selected from the right side of page 'The Issues', the links of related articles displayed at that moment are obtained on the fly using Live Search. Cool !!
Another perfect example of what can be done using Silverlight and Live search. Fantastic !
