One of these bluetooth messaging app was made by a developer who was on a cruise ship with family, and the Internet over satellite costs an arm and leg. So he wrote an app to communicate with his families over bluetooth.
Also why would one want to have the data go over some servers thousands miles away when the device is right next to you? Seems like bluetooth is the perfect way to communicate for devices that are close to each other.
