It's the stream; Facebook has a stream and Google does not.
After various experiments, I think people have figured out that the #1 way to make money on mobile is to have a stream of information that people willingly spend lots of time in. You just inject ads into that stream and bingo: profit. It's much harder for Google to win big here because while they have a very useful tool, people don't linger in it. They usually use it to get in, get what they need, and get out.

Twitter has generally done decently well on revenue per user (although that has performed worse recently as they've reduced their sales force). Twitter's problem, more than anything else, has always been increasing active users.
That's just the plan; you still have to execute capably on that plan, which is where Twitter falls down. Honestly Twitter could be healthy company- not as profitable as Facebook, but healthy- if they didn't have such incompetent management
