Ring a ding - shush.

As I'm just warming up to this blogging idea (why would anybody want to read my musings and why am I prone to so many typos when typing in this mode?) , let me travel the well-worn debate on policies that don't really work with the public, such as the great cell phone issue. Some libraries ban cell phone use because a few people make disruptive noise while using them. (Loud ring tones, or talking too loudly.) What most people agree now is that the disruptive noise not the technology should be banned. Does a person who answers their vibrating phone and speaks quietly into their bluetooth headset still count as a cell phone user that needs to be shushed or sent to the lobby?
