Unfriending on Facebook

So I am finishing up my final web project for this class and I have to say that it helped me to explore the different aspects on online friendship. One of the biggest things I got from it was that we cannot really define what a friend is for someone else. A friend may be someone that you can just go to talk to online when you need it. Someone who is there for you even though they are not physically there. My mom always told me that I would be blessed to have a real true best friend in my lifetime, and that all the other friends I have throughout life I would have to use them for what they are worth (but not in a bad way). She just meant that there are certain friends that I will be able to go to church with, some friends I can talk to, some friends I can have game night with, etc. So these online friendships can truely be genuine when you think about what its worth. I also can confirm that I still hate it when people on Facebook have a billion people they don't talk  to, are not friends with, and do not network with-MEANING YOU SHOULD NOT BE FACEBOOK FRIENDS! ;) I'm not as angry as that sounds. Tell me what you guys think!
