It should come as no surprise that knowledge workers spend more time online than your average Joe. US citizens who access the internet at work are online 3 out of every 5 weekdays, Media Metrix has found. Home users are online only 2 days out of 7. On the other hand, both groups are spending increasing amounts of time on the net. Work users accessed 69% more content in February 1999 than they did in February 1998, while for home users, access time has tripled since February 1996. News, information and entertainment sites top both groups’ access lists – ahead of corporate and porn sites, surprisingly enough.
