IM at work

A Microsoft guy writes a good article on why they are encouraging users to Instant Messaging at Work instead of email. I guess they have to use it at MS as they wrote a corporate version to go with exchange (and to reduce the load on their servers) but it still makes good reading. We use it internally too as its great for contacting the home workers when you want to find out the answer to a quick question or even if they are at their computer.
