More buzz around the net about another pretty cool looking Web 2.0 product - and like Silverlight, yes it's from Microsoft.  Currently in an invitation only beta (and yes we're hoping to get in, you can sign up for the waiting list here) Popfly creates mashups - combining information from unrelated web services - and does it with little or no coding necessary.

Consisting of 3 basic parts, Popfly includes the mashup creator, a web page creator that uses the same interface as the Office Live web page creator, and a Popfly space, where mashups can be shared, remixed, and rated.
