I was sitting in my home office tonight writing an article inspired by Chris Brogan when I heard some thumping sounds like someone slamming car doors outside. A few moments later I hear sirens. Since I follow our Fire Department I check Seesmic and sure enough there is a tweet right there: @srvfpd_danville STRUCTURE FIRE, 6 WOODSIDE CT, DANVILLE (2009-11-24 21:05:47) http://bit.ly/82vqTj I click the link and see as a crow flies that location is less than 1 mile from my house. Soon I heard more sirens, most emergencies handled by our world class Fire Department are medical emergencies. I am not sure if the door slamming sounds were in fact some tiny explosions inside that home, they may have just been car doors but one thing is for sure - I may have never known about the fire were it not for Twitter.
