Is it okay to start talking to the girl I like through facebook?

[-----]

I am asking this question because I have a hard time talking the the girl I like. I think there is a chance she might like me back. We've talked before so it's not like she has no idea who I am. I was thinking of facebook chatting a few times. Would it be awkward if we only talked a few times this year in person? Also if your a girl, would you like it if a guy facebook chatted you?

If you have things to talk about, it won't be awkward at all. I'd like it if a guy facebook chatted me, especially if I liked that guy.
