Helping open the floodgates.
"People often dont believe me when I say how important it is to have efficient communication within a business. And when messaging is mentioned as one of the most efficient means, the floods of doubt open up. However, until youve tried messaging within the company, you dont know what youre missing."
I've had MS Communicator on my desktop for a couple of years now. Chat / instant messaging (is there a difference?) may be efficient, but I don't know of a situation where it would be my first choice from my available communications tools. Holding a phone to my head may be inconvenient, but to me the speed of voice communication more than makes up for it.
