Here's an intersting article about using social media at EMS. If the PIO's were able to use facebook or twitter to update the public about the goings-on such as mini-press releases, Community Outreach projects or CPR classes, it could be a valuable tool in making a positive impact for EMS in the city. Since social media on the internet is a worldwide phenomenon, EMS could have a positive image of community involvement and responsibility that extends all over the world. Might be worth considering.
