I'm thinking banning e-mail at work won't catch on here in the U.S., but it is an interestig concept. How many time has someone mis-interpreted the "tone" of your e-mail? How about that person that always seems to be the shy person, but sends out harshly worded e-mails all the time? With this approach, it forces co-workers to actually talk out their isuues. Still not something I'd like to see happen, but the concept is interesting.
