Facebook: Crucial or Trivial?

[Heisenberg]

How important do you guys think facebook is, especially when it comes to girls?

I never had one. I'm pretty introverted and the concept just isn't interesting to me *( I do like people, and interacting with them in person)*. Now I'm giving it a shot, but I'm not really seeing the point so far... I don't really like spreading trivial details about myself online, so I keep my profile pretty brief. Then I gotta spend time searching through old highschool alumni/ friends of friends of friends, adding people I barely know just so I don't appear like the only one with no friends (which seems to equal any less than 100) Everyone who's a real friend or family member already knows how I'm doing and can call me anytime, but if I kept it to only people I see regularly, I'd have no more than 20 friends and the whole thing would be pointless as I have ways of contacting them IRL already...

I figured it could be cool for random girls I've met, but that seems pretty meh as you have to look through a bunch of people, remember last names, etc like a stalker.

Is it about filling your mind with details of people you hardly see so you can feel more connected? What happened to mystery and catching up with people in person?
Maybe I'm just super introverted/ slightly anti-social and don't "get" it.

Is it unhealthy if I don't care that a friend I haven't seen in 4 years from high-school who moved to Toronto went snowboarding with his girlfriend on Saturday... does that mean I'm just not a people person or hermit in the making? Is facebook more for people who try to stay super-informed and connected on everyone? Is it necessary to being a well rounded human being to have one? Should I put in the effort to market myself with cool pics and posts about what I do all the time; or just accept that I'm not that kind of guy and delete it?

I feel like not having one makes me a social outcast... but the thing doesn't interest me at all.

What do you guys think?
