Do you use instant messenger for business ?

I use it a lot for business, I have all m y co-workers, some clients and suppliers too, but as always, it is catching up in Europe later than in the US.

Radicati Group projects 670 instant messaging users by 2008. Don't rush to invest in that custom IM development company yet, as up to 88% are predicted to use the freely available tools and networks for their daily communication. The market itself, however, will fetch a nice $413, but only in 2008. Globally only 20% of the corporate users think of IM as a valid communication tool for doing business. By 2008 this will quadruple to 80%, where it turns out that the United States is already ahead of the world - 85% of Americans consider instant messenger to be a viable business tool today... via Always on
