I got a new phone number the other day. I shared it with several friends via mass text messages. These are close friends, but many of them I don't talk to on the phone all that often. I also learned a valuable lesson. While my phone company doesn't have a 'reply all' feature on mass text messages, it is apparently the default on many other phone carriers. Some people received my notification that I had a new phone number 10 times. And they heard about my plans to drink beer over the holidays.
