This finding challenges a long-held assumption (of mine, at least) that as the Internet matured, it would be used more to complete specific tasks. Pew doesn't say this, but an implication may be that we're returning to the days of "surfing the web". I thought those days were over.
The Pew research didn't ask respondants their definition of "fun" or "to pass time", so we really can't make sweeping conclusions; nonetheless I'm surprised by this report. How do others interpret it?
