Pinterest ($PRIVATE:PINTEREST) is popular. Really popular. It's now been the most-popular app logged into via Facebook login for three months, once again beating out Spotify ($SPOT), Candy Crush Saga ($ATVI), and Tinder ($MTCH).

The image, art, and idea sharing app continued its popularity run in November with an average rank of 2. In fact, it distanced its lead over the number-two spot Candy Crush Saga which showed an average use rank of 5.86.

That also means that Candy Crush Saga displaced Spotify in the second spot this month, with Spotify moving down to an average rank of 6.43.

But something more peculiar in this week's rankings isn't within the top-5, but rather with Quora ($PRIVATE:QUORA).

In November, the Q&A website jumped to the tenth-most used app via Facebook login last month. Coincidentally, Quora is in the throes of a massive data breach that exposed login information for 100 million of its users.
