popfly is a new…uh…api(?) microsoft put together that is basically a drag and drop widget mash-up tool. the idea behind it seems like yahoo pipes to some extent, although i never spent any time with pipes so i can’t give a real comparison – someone will i’m sure. it requires silverlight 1.0, but doesn’t yet support 1.1. it’s all client-side, which is pretty cool and allows you to share your creations with your friends or the world. the collaboration aspect is intriguing as this could lead to some very powerful and useful interfaces. i’d be interested to see the scaling capabilities of this as that will be a really big factor in popfly’s success.
if ms does this right, it could be very big – so here’s to hoping that they do it well and respond to the feedback of the testing groups. they seem to be giving the collective a bit more input into their products these days and this would be a great place to allow the community at large to get their hands in the microsoft sandbox.
