Talking about Twitter in the same breath as YouTube just doesn't make sense - YouTube's troubles stem from the fact that its costs are through the roof, being a streaming video site and all. In order to come out of the red, they have to make a pretty large amount off of each viewer, and that's tough to do when advertising rates are depressed. Twitter, on the other hand, sends 140 character messages back and forth. Yes, they've had scaling issues, but that's because they blew up from a tiny operation into a major success overnight without the manpower to handle the growth, not an indication that their costs are too high. If they flip pretty much any monetization switch, they'll become profitable quickly.
