A couple of months ago, John Montgomery gave me an invite to test drive a new Microsoft project that was billed as a mashup builder. It's been on my list of "cool things at Microsoft I've been asked to check out but never investigated deeply enough" for about three months [until recently this list also included Microsoft Scout]. Thus I was quite surprised when I found out that the project was already ready for release and had been renamed Popfly.

The most succinct description of the project I've seen is Mike Arrington's writeup in his post Microsoft Launches Popfly: Mashup App Creator Built On Silverlight which stated

Microsoft will announce the private beta launch of Popfly this morning, a new Silverlight application that allows users to create mashups, widgets and other applications using a very cool and easy to use web-based graphical interface.
Popfly is a big leap forward from the competitors above because it lets you do so much more, and it is one of the nicest web application interfaces I have ever seen. With Popfly, you can create applications, mashups, web pages and widgets (gadgets) and it is all tied together in a social network (as part of the Live Spaces platform) where you can connect with other users and publishers of applications. Mashups are created by dragging in and connecting ‘blocks’ which produce an output. Blocks are modules that connect to various web services API’s, and even today there are dozens of different blocks that work with a whole variety of different web services.

See additional screen shots and a link to a screencast on the Popfly overview page here.

The application is an impressive mashup builder. It's at least on par with Yahoo! Pipes or maybe even better since it lets you mash up not just RSS feeds but also APIs from dozens of different sources including Flickr, Digg, Twitter, XBox Live and Windows Live spaces among others. Did I mention that it is also a great demo of the capabilities of Silverlight? Damn, the Microsoft developer division folks are outdoing themselves in 2007 and it isn't even June yet.

John Montgomery has a roundup of all the recent posts about Popfly in his blog post Some of the Popfly News So Far. I've been told I have three invites to the service to give out. The first three non-Microsoft people to ping me at my work email address can have them. The invitations are gone.

Kudos to the Popfly team on such a kick ass release.

Don Quixote mode:

Popfly, not PopFly as in the topic... And to reiterate my quest for understanding this issue: what is it with English speaking people and their PascalCasing of concatenated words in names? Is that concept really that hard/uncommon to grasp? Well, Firefox is not really that wide and neither is Silverlight and Popfly is even shorter, especially compared to the German main example of Donaudampfschifffahrtskapitän, but I see them erroneously spelled as FireFox and SilverLight over and over again...

Disclaimer: FireFox has been my pet peeve since some time now and I am just wonder why this happens (e.g. it never was PhoeNix or MoZilLa...) and it happens with SilverLight and PopFly again so I really am curious about the reasons.

The TechCrunch blog post you reference was written by Nik Cubrilovic, not Michael Arrington.
