Did I get enough exercise today? How many calories did I burn? Am I getting good quality sleep? How many steps and miles did I walk today? The Fitbit Tracker helps you answer these questions.

The Gnip API provides notification of activities (events) occurring in a variety of services and, whenever possible, a guid that identifies the activity itself vis a vis the service it was created on. Activity examples include a user "tweet" (twitter), a user "dugg" (digg), a user creating a blog post, etc.
