Is it weird if I come out to my feelings about this guy I like on facebook because I'm too shy in person?

Ok! So there's this guy I have been crushing on at college and for the life of me I can't bring myself to saying two words to him in person and have just been giving him bodily signals that I like him all semester. I can't really tell if he likes me or not. We've sat at the same table on semester and he has smiled at me and is nice but that doesn't mean anything. Anyways, I just came past his facebook account (YAY). Anyways, I want to come out about all my feelings and tell him I'd like to go on a date but how I'm not sure whether or not he's gay. It's all about a page long and I've typed it up on Word. It speaks to how everyday I get nervous because I'm so crazy about him but to scared to say anything. So yea! I was about to send it to him on facebook but thought I'd come here to verify if it was a good move. I say what the hell. I'm not afraid to get rejected over the freaking Internet. Now as for in person, hell yes!
