Well, to be fair, they have turned a profit far more often than not. They lost money in Q3 2013 (and in 2013 over all). But Q4 2013, and Q1 2014 have since been profitable for them. Also their expenditures seem to be paying off, as they had a 27.1% growth in revenue 2012 to 2013, and predict the same level in 2014.
