Facebook Friend collectors

I've been getting a few facebook friend requests lately.  Some I know, some I don't.  Either way, I noticed something about facebook.  I love facebook.  It's so nice to be able to keep up with family and old friends and people I hang out with currently... or just whomever.  But the last year, since I've discovered the false-ness that can be friendship and the two sided people that I get involved with and the lack of sincerity in friendship in general I've really started rethinking my facebook friends.  Why do I need to be "friends" with someone I never talked to a day in my life until I joined facebook?  Why am I friends with someone I used to know 15 years ago when I was in high school and a completely different person, but we did not value our friendship enough to maintain it over these last 15 years?  Why am I friends with people I generally don't care about?  Who do I want to be "friends" with?  I'm friends with my sister, my daughter, my mom, my step mother, my aunts, my grandmother...  You get the idea.  Being friends with family is important because like my cousin said, it makes it feel like family is just down the street, not across the country.  I like watching my cousin Katie grow up, succeed in college, become a beautiful young woman.  I like seeing my sister and her boyfriend and all of the fun things they do.  I can be a part of my family's life even when I can't be there.  And, likewise, I can let my family watch the girls grow up and be a part of our life even though they are hours away.  But what about these *other* people?  Do I approve their requests?  Do I collect friends like coins that I have somewhere, but never look at or care about?  Do I let these other people see my life and what's going on?  Do I become another of their number?  When they have 200, 500, 1000 or more friends, do they even know I'm there?  Do they even remember me?  My one status a day... does that really come up in their feed?  Am I the only one that doesn't want to collect friends on there?
