You're only looking at one side of the coin. If you look at it from a FB stand point, FB connect is effective whatever the market.

See you can make money in a casino, some games offer better chances than other but in the end it's always the casino who makes the real money.

You may have misinterpreted what I said because I don't quite get what your point. FB connect is not effective for certain markets. Good luck getting cryptologists signing up for your FB Connect website.
