NEW YORK (AP) — The little blue bird is flying high. Stronger-than-expected financial results pushed Twitter’s stock sharply higher on Tuesday after the short messaging service said its revenue more than doubled in the second quarter.

Twitter also grew its user base more than expected, alleviating concerns, at least for now, that it doesn’t hold appeal for a broad swath of people. Its larger rival, Facebook, also posted strong results last week and its stock is trading near a record high.
