Is there a need for more privacy online?

The USA Today has a news story discussing the current push by consumer and privacy advocacy groups asking Congress to begin to protect consumers rights online. Currently, online sources have free reign to collect data on habits to predict one's internet search. The Interactive Advertising Bureau is strongly opposed to regulating privacy on the internet, and this is the first time advocate groups have spoken out against the advertising policies online.

While tracking internet habits is critical for a business, do sites like Google need to be freely monitoring all internet surfing habits? Should Congress listen to consumer groups and take steps to protect internet surfers privacy?
