Indian Business Loves e-mail, Should It?

Economist reports on a fascinating Grant Thornton survey where they asked businesses if e-mail and internet increased employee productivity.

8o% of Indian businesses said yes even though their employees spent on average 2 hours on-line every day. In the US and Hong Kong, where employees spent a similar time on-line, only 48% of businesses thought this added to productivity.

Does this mean Indian e-mailers are more work-focused than American e-mailers, or does it mean that Indian businesses don't really know what they're talking about?
