Conference Calling From Blackberry

What is so difficult to communicate?
I'm doing an informal investigation of a series of articles on the domain of success communication technology in the current business environment. Cell phones, Twitter, instant messaging, conference calls, Videoconferencing, etc. The question for you is: What are some things that drive you crazy on how people use communication technology? Examples: – That guy with the blue tooth headset on the subway, almost shouting as he struggles to participate in a call. Unfortunately, everyone within 20 feet is * also * in the call. – The girl at the bottom of the conference room just looking up from her Blackberry as she "participate" in the meeting. What Do you struggle with?
People who use Facebook on their iPhones and not see where they go.
