There is no real comparison. Twitter is unique in its market (where it makes money). You can't really compare it to Facebook.
But your point about Twitter's uniqueness is also valid, and something I hadn't seriously thought of before. Around the time of their IPO, I think the general analyst consensus was that Twitter would not make money and their stock was not a buy. It makes sense because their product is wholly different from the suites offered by Facebook or Google, the companies this article and the commenter compare it to. Perhaps the other stakeholders understood this aspect of Twitter and didn't expect large returns from day 1.
