Whatever you think of his politics, Barack Obama has certainly made good use of mobile technology. He announced his choice of vice-presidential running mate via text message, although the media scooped the news by a few hours. Imagine the nervous excitement at Distributive Networks as they pressed the “send” button for that message, which reached about 2.9 million people.At the Democratic convention this week, attendees will be asked to send text messages to family and friends, and also invited to make calls from provided phones. The campaign will capture those dialed numbers for later use. With all those text messages and phone calls from Invesco Field, the mobile networks will face an extraordinary load. Many communications companies, including Cisco, are helping connect the convention.Meanwhile, if politics just aggravates you, how will you react to receiving such text messages? You could hurl your mobile phone in frustration. You could even enter the Mobile Phone Throwing World Championships in Estonia. But you’ll need technique as well as vexation: the winning throw was 85 meters (279 feet)!
