Wonderful
If Microsoft want to patent the way we are allowed to finish our conversations- why don't we just throw in the towel and give them the list of all our colleagues and let them converse with them on our behalf. I'll hang-up on someone if I feel like it, ignore someone I had a falling out with over the weekend, or chat up my wife on IM as I see fit. This proposed patent is a good reason to hang up our keyboards altogether and actually start talking to people the good-old way again.......errrr most probably by Skype or mobile phone........
