Limits on kids' online activity considered by senators

Has the danger for children from social networking sites, cell phones and the web grown strong enough that it's again time for the government to step in to set some rules?

Senators asked those questions today at a hearing of the Senate Commerce Committee panel on Consumer Protection.

A decade after Congress enacted the Children's Online Privacy Protection Act, a law which requires web sites wanting personal information from kids under 13 first get a parent's OK, some senators expressed doubts that the law goes far enough.

"Clearly the online world has changed dramatically," said Sen. Amy Klobuchar, D-Minn. "It's very important we examine this rule so we keep up with technology."
