The layman knows a Tweet as a short post consisting of no more than 140 characters. To developers working on the Twitter platform, however, a Tweet contains far more information. It contains stuff like the user's account creation date, number of followers, preferred language, and even location and timezone.

To developers building tools on top of the Twitter platform, they know tweets contain far more information than just whatever brief, passing thought you felt the urge to share with your friends via the microblogging network. A tweet is filled with metadata - information about when it was sent, by who, using what Twitter application and so on.
