Like Silverlight? Like search? Like them combined? If so be sure to check out the new Tafiti search engine. I especially liked the treeview option where you can see, in a rotating tree, what's been found. Probably it won't replace, for me anyway, google or live search but it shows the possibilities that you can obtain when using Silverlight.
Speaking of which, if you're in Belgium on September 20th you can join the VISUG meeting about Silverlight. I'll be there too.

Grz, Kris.
