Some of these advertising-related problems seem to be related to Twitter's ad delivering mechanism offering too much transparency into the effectiveness of the advertising, while other networks profit from opacity. In other words, by letting advertisers be more efficient, Twitter should have a better handle (and perhaps later, collect a premium) for the value inherent in better matchmaking and conversions. Is there a path for an efficient social network that has the right buyers and sellers on it transacting in highly efficient ways, but which isn't beholden to conquer-the-world MAU metrics that have it scrambling to attract the masses at the lower end of the Facebook curve (e.g., old high school acquaintances who find it the perfect outlet to display their self-betraying views on conspiracies, politics and race?)
