If this goes further it's going to be frustrating to get information about public services. My local fire department has a Twitter feed where they tell the public about areas to avoid. Both local public transit systems use Twitter and it's often the best way to know about real time delays and issues (often in replies rather than main-feed tweets). It's already bad enough when these things are on Facebook, but I always appreciated when they're on Twitter and visible to everyone. It seems like now that might be changing.
