It's interesting, because my interest and understanding of social network is that it's precisely for managing my distant relationships. People I went to high school with, people I worked with 5 years ago, my second cousins, people I somewhat know who I may need to contact at some point.

People I'm close to, "the people I love", I've never had a problem keeping in touch with them. I have their number in my phone, I have their email address, I see them regularly, I know what they're up to, and how to contact them. That's never been a problem, and social networking hasn't really changed that for me.
