I've had a number of conversations over the last couple of years about handling the amount of information and contactability that is "available" to us these days, if not pressed upon us .... including some conversations with people who may be reading this blog.
If that topic interests you, you may well be interested in this article about Bit Literacy (http://www.goodexperience.com/columns/04/0128.bitliteracy.html) which Dave put on his site and which I found quite interesting.
