Recent studies indicate that people who spend significant time browsing the World Wide Web do so at the expense of time spent in face-to-face interaction with other people  This has led some to fear that social isolation will greatly increase because of the popularity of browsing the Web
But, since browsing the Web is just one of many popular solitary activities, and any time spent on a solitary activity is time spent not interacting face-to-face with other people, such fears are unwarranted
It is the claim that the argument attempts to undermine.
