As you may or may not of heard, Microsoft annouced an private alpha release of Popfly last Friday.

Popfly is an online tool for creating 'web mashups' by allowing you to connect web services and API's together in an easy to use editor.

The tool is built on Silverlight and looks very cool, I definately think we will be hearing about this alot more in the near future.

Registration at the moment is invite only so you may not be ablt to get a look at it yet.

In the meantime check out this Channel9 video which will give you a good sneak preview of what to expect.
