Many Americans are jumping into the fast, mobile, participatory Web without considering all the implications. If nothing really bad has happened to someone, they tend neither to worry about their personal information nor to take steps to limit the amount of information that can be found about them online.

Internet users who said they had not encountered spyware were less likely to view it as a serious threat and more likely to say it's just part of life online.
