Sure. In that measure of success, it's wildly successful. But it's not a sure thing they'll be able to monetize it well. Surely the value should be measured based on how valuable it is to each user * number of users. I'm not convinced that's as high as people think. Their retention rates aren't great at all. But if the measure of success is 'can we hype and sell', then definitely twitter are already wildly successful and I'm sure they'll all do fine out of it. (Then whoever buys will probably completely kill it and the cycle will repeat).
