A widget displays Web content from external sources and can be embedded into a blog, social network, or other Web page, or downloaded to one's desktop. With widgets--sometimes referred to as gadgets--one can insert video into a blog post, display slideshows on MySpace, get the weather delivered to his mobile device, drag-and-drop his Netflix queue into iGoogle, and much more.
