Microsoft release Popfly to public beta today - October 18, 2007. This comes shortly after the Fall Release of Live Search, Live Search Mobile, and Live Search 411.

Popfly is a web tool bases on Microsoft’s Silverlight that allows people to create or edit their own mashups. These mashups can them be used in a web application or on a personal web site like Windows Live Spaces, Facebook, or MySpace. Popfly has on-screen tutorials that walk you through creating a web page or mashup. I created my first mashup in Popfly in about 10 minutes, without ever having used Popfly before. It’s a cool tool for non-developers to be able to create mashups, webpages, and add applications/games to their websites.

See the Vitrual Earth /Flickr Sunset Photos Mashup created using Popfly.
