Google's New +1 Social Search Button Puts 'Likes' in Your Search
Launching experimentally today, +1 can only be used on Google's search results pages, but will eventually be accessible from other links. Sites like Facebook, Twitter and Tumblr have proven to be helpful alternatives to search for finding and sharing interesting content, and Google's hybrid approach, with a potential user base of millions, could help improve the quality of search results.
As Google finally settles with the FTC today over last year's Buzz privacy disaster, it's notable that contacts and privacy are again an issue. With followers, contacts and profiles littered across Google's Gmail, Google Reader, Talk, Buzz, Profiles and other services, exactly to whom your +1's go remains unclear.
