A company would be crazy to ignore FB. I don't use it, but the number of people who do is staggering. And not only the breadth, but because the data is structured, ads can be much more precisely targeted than any TV commercial.
How neither FB, nor Reddit, nor standing on a street corner wearing a placard, addresses what I feel the the elephant in the room. The fundamental failure point.
According to the last stats I saw Hitech post, conversions rate is "around" 1%. Something about the player experience is not closing the deal. Unless you can improve that, you are mostly whizzing in the wind. But it doesn't hurt anything if it uses volunteer effort, but it is the reason it doesn't make sense to throw money at the marketing until you can raise that success rate. You'd be better off just burning the money to save on heating costs.
