Breaking with presidential punch line tradition for the second consecutive year, Obama dropped zinger after zinger on his opponents and allies alike at the annual White House Correspondents' Association dinner. Obama went all Don Rickles on a broad range of topics and individuals: Vice President Biden and Secretary of State Hillary Clinton, presidential advisers David Axelrod and Rahm Emanuel, the news media, Jay Leno, and Republicans Michael Steele, Scott Brown, John McCain and Sarah Palin.
To find the hottest restaurant, bar or concert venue in town, many young adults are no longer checking in with their friends. They're "checking in" virtually via Foursquare, a location-based social networking site. Participants log onto the site and "check in" via smartphone to let contacts who are fellow users know where they are. At the same time, they learn what those users are doing — whether a co-worker is eating at the restaurant next door, or if friends are gathering at a nightclub across town. As "check in" alerts are traded between phones, the people attached to them instantly become aware of the spots that are popular in their social circles.
