Late this afternoon the sky was looking ominous and one of my coworkers said his girlfriend sent him a text message to tell him there was a tornado warning in effect.  I went back to my desk to check it out. But did I pull up weather.com or even our local paper online?  No, I immediately went to Twitter and, sure enough, people in the Milwaukee area were tweeting about the current conditions.  That led me to follow the weather Twitter accounts for two of the local television stations.  I wonder how many others out there are turning directly to Twitter instead of turning to their old standbys for news and information like this?  Interesting.
