The thing about Twitter and Facebook for marketing is that it's an "OPT-IN" situation. If someone starts following your facebook or your twitter that means they have decided that they have enough interest in you to want to see what you are doing. That's the #1 reason it's more successful than carpetbombing people or doing ads or cold calls, or target marketing or spam or whatever. People decide that they 'want' to hear from you, so all you have to do is provide them with quality information to keep that relationship happening.
