No. Facebook doesn’t somehow prevent me from being able to figure out how frequently I actually see people. And I can’t really afford to see those who don’t live nearby any more than I actually do, both financially and emotionally. Even those who do live nearby, I could technically see more, but doing so would interfere with my ability to do other things, like schoolwork; I can chat with someone or catch up on Facebook while writing a paper, but if I hang out with them, it’s normally considered rude to do other things while hanging out with them.
I also don’t think seeing them more would actually be preferable. Being around people physically is emotionally draining, even when I love them. Facebook (and social networking in general) allow me to have more interaction with people, because “I’m tired/cranky/distracted/yearning for jammies” doesn’t have to mean I can’t interact with people.
The people I have the least contact with in my life are the people who aren’t online (regularly). The ones I have the most contact with, both online and in person, are online all the time.
