>You can't DM someone that you don't follow. Twitter already exposes all the text of non-protected accounts to advertisers for their contextual ad products. I agree but think about it this way. I follow Starbucks because I like them and visit them often. Now I see a link for discounted Starbucks coffee on Amazon and purchase them via twitter. Prior to that Starbucks had to make assumptions or run some machine algo on my tweets to determine: a) I am not a bot and b) My loyalty can or cannot be leveraged. However with this purchase, whenever they bring out a new flavor they could be certain with some confidence that I would make a purchase, thus messaging me personally or including me in one of their tweets. Its not necessarily a bad thing but history has it that convenience always has its price.
