Social networking sites - love or loathe

I am fairly ambivalent about social networking sites. I have a facebook page that I use marginally. I find myself wondering about the amount of time some people must spend on the site. Either posting comments or also finding other sites or photos or YouTube items to post. Where do they get the time? I feel that it is very much a young persons activity. They seem to revel in the instant communication. They appear to rather sit in their rooms in front of a screen than catch up with friends in real time. If social networking disappeared overnight I wouldn't be phased. So, I guess you could say that I am veering toward the loathe of these sites. I love catching up with news about friends in actual person to person contact. I consider myself old school, still loving collecting cds instead of using an ipod, preferring maximum security for my use of any site instead of sharing with everyone. However, I am really interested to see where social networking sites go to from here. Whether in a few years I too will be hooked on instant comunication via these sites. We will have to wait and see. Now that maybe worth waiting for.....
