One of the big news items of today is that Microsoft’s mashup utility, Popfly, is now open to the public.
About two months back, I was able to get access to Popfly. There wasn’t much capability at the time and the interface was quite confusing.

In case you haven’t heard of it, Popfly allows people to create applications, mashups and webpages with having to know html.

Right now, Popfly serves as a third-party application and uses existing resources that users have on sites like Facebook and Flickr.

To create mashups on Popfly, and even view certain tutorials, you need to download Silverlight.
