Is this a good way to come out?

I've already told my close group of friends (but 1) that I'm gay and luckily they're all super cool about it. I've also told 2 girls I know well and trust that I'm gay.

Now, since I don't feel comfortable typing something out of Facebook, and am mediocre at conversation, I was considering an idea I've seen floating around here.

Would asking the 2 girls I know to 'spread the word' of my gayness be a good idea? I know a lot of kids in my class, and I feel like they'd be cool with it for the most part.

What do you guys think?
