I'm having a blast with Popfly, Microsoft's Silverlight-based mash-up designers. I've created a block that uses AOL Video Search and made a simple page that shows the results of what it does. I fell as if I'm just scratching the surface of something really cool! The mashup below creates a bar graph that you can see on this page. The Popfly team really did an amazing job in using Silverlight to create a very cool experience. Now that it's in beta, anyone can try Popfly and create blocks, mash-ups, pages, even a community. I can't wait to get my hands on the OpenSocial API! This will really be fun to mash up in Popfly.
