I am paying attention, that is why I question the very existence of these types of sites. Everything you mentioned was possible long before the invention of the telegram... what is your point? I will stick to my guns here: Most of these sites tend to afflict one with or are used because of ennui, in my opinion. Beyond that... nothing.

A number of my good friendships would not have existed without Facebook to bridge the gap that a traveling lifestyle created between our initial contact and our later co-existence.

Could we have simply sent letters, or emails? Yes, but we probably wouldn't have done this. Does this benefit offset the negative impact of sites like Facebook? I don't know, and I think it's too early to tell.

But to say these sites are not useful is a bit too extreme a statement, in my opinion. I know many people who happily use social sites just to augment their social lives...
