In my column series 'The Main Thing', I often talk about how Internet technology can improve the way people communicate - both within a business and between a business and its customers and partners.

After all, it's the future of business communication that we're looking toward.

I want my testimony to stand on that point. But I would point out that Zona Research Inc. showed we have increased market share among business users, educational users, and government users over the past several months - and that's more recent than the IDC report.
