Why is my real name listed instead of my nickname?

Babykegs

On the left side of game of candy crush saga, it shows my real first name with a question mark underneath. Why doesn't it show my nick name? Why aren't there other names listed also? What is the difference in playing on Facebook and playing on king.com? I'm confused on which way I should be playing. Thanks for your help.

If you're connected to facebook you will see your facebook friends and your name from your account. If you're connected to the kingdom then you will see your nickname that you choose and a list of local people that also play the game. Of course by saving to the kingdom as well, your progress is more safe because if anything happens to your facebook account then you could lose your progress etc.
