David's raised a good point there about the fact that communication is far more effective when it's verbal - although I would have to play Devil's Advocate here and suggest that what the internet does is that it makes the physically impractical much moreattainable by providing alternatives. So, whilst it's not easy for me (based in Edinburgh, Scotland) to meet with a client in (say) Boston, USA, in a reasonable space of time, the internet may allow me to have an online communication session, either using 'conventional' e-methods (email, fax, etc.) or by more sophisticated methods (video-conferencing, chat, etc.).
Of course, technology provides us only with a tool to communicate, so without an understanding of effective communications and inter-personal awareness, it is of less use. I see it personally as a way of adding to, rather than replacing, existing methods (eg. phone, fax, etc.)
