I found this a while ago: 'Shy students who use Facebook have better quality relationships"
And a lovely piece from Danny O'Brien which echoes what I've always thought - one of the reasons people (some people, at least) like blogging is because they can express themselves without having to meet anyone.
And, if you do want to meet people, it's a way of getting to know them first, so you don't have to deal with all that awkwardness at the beginning of a conversation. You're already through all that via the internet.
