I totally agree with you about everything you said.
I also believe that the social aspect of Facebook is absolutely pathetic, people don't act like how they originally do in person because on Facebook we mostly talk with our minds, what our brain basically wants to say, but when you're in person, it is a lot less simplistic to pretty much talk in person because it's a bit harder to talk your mind, you aren't exactly in Private when it comes to talking to people in Public places, where as, on Facebook, you can talk about whatever you want to talk about without people even knowing that you're talking about it.
You also can be anyone via Facebook, you can make your own identity and hide your true identity by saying you're a millionaire when you actually quite poor or... you can act nice when you're actually a really really mean type of person in person. With Facebook, these things have been made possible. And that is just what I hate about it.
And oh my God, I totally feel you about those status's you see on your Home Page. I got to a limit where I had enough of seeing those crap status's, those status's that say "Like if you wish cancer never existed." HA! Liking a status ain't going to help anything! I got to a limit where I just blocked my whole home page up so I have no access to it at all via this Google Chrome Add-on called "AdBlock"
But however, I think I am trapped inside Facebook all together, caved in with no way out. Because I am now just extremely addicted to it. Because most of my friends are on there and it's the only way I can actually keep in contact with my friends outside school. And if I am to organize meetings with my friends, the only way of organizing is via Facebook. Which sucks.
But however, if you are very determined on doing so, I believe you should delete it. Or choose your second option in deleting all your friends and use only the fanpages.
I hope I helped.
