Twitter recently launched its location-based service that allows you to embed your location in the meta data of a tweet on a case-by-case basis. Your location doesn't appear in the tweet, but underneath it along with other information like the time you sent the message and which Twitter client you were using (twitter client, Website, iPhone app, etc.).

These are just a few of the many location-based services and games available today. Do you have a favorite location-based application or does the whole idea just creep you out?
