widget \noun\ a small independent chunk of web code, created by a third party, that can be used to provide specific functionality or content to a website or other web enabled device, like a Chumby.
For example, Chumby users can download a Facebook widget to access their profile. This widget wasn’t created by the Chumby people. It was created and is managed by the Facebook people as its own separate little application.
Widgets are everywhere, weather window on a website-widget, all those clever Facebook applications you add to your profile-widget, YouTube window embedded on a homepage-yep, you got it, widget. The beauty of widgets, is that you can have an unlimited number of third parties creating great content and applications for regular people like us, instead of one company trying to do it all.
