Then, I began to understand. There were applications that I got hooked on. Suddenly I was spamming my friends with app requests and I didn't like that. It was then that my own friend list began to grow. It was then that I began accepting friend requests from those who I'm not really 'friends' with. I feel no guilt about spamming those I don't care if I piss off. Heh.
So, that which I didn't understand has now become my own common practice and my fb strength grows by the day. Power in numbers.
