I don't use twitter so if I'm wrong about this, I stand by to be corrected, but with twitter, I thought you can only reach people who have already chosen to listen to you. It's powerful in that it's fast and can reach your followers quickly, and hope that they pass it on to non-followers, but it's fundamentally restricted in that you can't twitter to people who don't already follow you; the very people you need to reach most, given that followers are self-selectingly already on-message.
