For those that are still using BBM and got the update last week for iOS and Android, check out the Glympse feature. In a BBM conversation click on the paperclip next to the line where you type. Then click on the "G." This allows you to share your location with a BBM contact for any length of time between 5 minutes and 4 hours. I have found this to be incredibly useful.
Example: You are meeting up with someone, you send them your location and they can see where you are so that they can meet you at the right place, know how long it will take you to get there (it also shows how quickly you are moving so you get a sense of if the person is in traffic or not)... When my wife and I are at outlets or some mall we always go to different stores and then at some point I call to ask which store she is in. By the time I get to that store she may have moved on to a different one. Now she just shares her location at the beginning and then at any point I can meet up with her at the store she is in.
The uses are really endless.
