Having been in a friend's wedding that I met on OD, I really have to disagree about those friendships not being as valuable! There is something to say for having friends at a "see you in person in 10 minutes" range, but I don't think that diminishes how real "online" friends can be. Every single person I've met up with in person who was first an internet friend have been awesome and a real friend, not superficial. I have certainly found it harder to make those friendships in person as an adult who moved to a new state. I am a huge proponent of meeting your online friends! (while being discerning, of course.)
