I love Facebook, but I do have a few things I dislike:
-when I ignore a friend request, and they friend request me again...and again!
-I feel guilty if I don't accept a "hug" or "good karma".
-I feel bad when married couples have to announce their divorce via the relationship status feature. There's no private way of removing/changing your status!
-I don't like when people write on my wall (which I have since removed) to make plans...I would feel bad if someone else saw it and felt left out.
-I don't like when people take FB too seriously.
-I think it's unfortunate that friendships sometimes end between people because of FB...
-And I agree with so many other people's comments regarding this post as well
