I'm looking into using Twitter to keep me informed about emergencies or anything else that we boy scout types might want to keep abreast of. So I'm following snow emergency alerts from the city. Thus far no news, and that's a good thing. I also started following the local police, but that turns out to be rather useless for my purpose. Great for looking for a cookout to go to in my area. Those of you who use Twitter, what services should I be looking to follow?
