The surgeons at Henry Ford Hospital are Twittering again from the operating room. This time it's during a robotic-assisted hysterectomy. When I asked the hospital's manager of web services why they were using the technology -- which broadcasts short messages to a web audience in real time -- he said they hope to inform the public about new procedures and treatment options. You can follow along by going to twitter.com and searching for HenryFordNews. Do you think that's an effective way to inform the public?
