Widgets. Before you say huh, I'll tell you: A widget is the collective name used for small, embedded application that can be selected to provide additional features or functionality on a self-selecting basis by a user. The majority of blog servers and social networking sites are offering a vast array of widgets that users can embed into their pages and profiles that can be accessed from computers as well as cell phones. Advertisers are also signing on, understanding the power that widgets can have in promoting word-of-mouth.
