脸书到底有多盛行，有多方便，我们来听听哈皮和毛拉是怎么说的吧。

Sample transcript

Harp: So Facebook is a social networking website. You have a profile and you can put pictures up, you can invite people to different events, you can join different networks. It is basically a way of keeping in touch with your friends.

Maura: Right. So before they had MySpace, which was pretty popular and I know in Japan they have Mixi. Do you know any other ones?

Harp: There is Bebo, I think that’s in South Korea and there’s more out there.

Maura: Right, social networking sites are everywhere but Facebook is for sure the biggest one in North America, in Europe as well. It’s almost everywhere now.
