Another interesting new Silverlight application is entering beta! For those unfamiliar with Microsoft Popfly, it allows users to easily create web applications without programming in APIs and without having intimate knowledge of Javascript. From the Popfly informational site:

Popfly is the fun and easy way to build and share mashups, gadgets, and Web pages. It’s made up of online visual tools for building Web pages and mashups and a social network where you can host, share, rate, comment and even remix creations from other Popfly users.

This will be great for people who want to add a little jazz to their website, Facebook page, etc, but don't have a programming background. With more of a drag and drop style, people can quickly create applications by pulling "blocks" from other sites and linking those blocks together.
