How to get to know your partner better in a long distance relationship?

I am in a long distance relationship right now and i now know everything about my parter. I know everything is to know about him, except for the physical of course.:( Long distance relationships are very hard mind you. For me, it has got to be the hardest thing i have every done im my life. But the rason i know everything about him is, all we do is talk. At first we took turns answering questions about each other and after a while you learn to get to know that person on a much more personal level. After that you just talk, and i mean really talk.
