If you don't get it then that line of thinking is not for you. Different people like different things. I left FB a few years ago now and do not miss it one bit, whatsapp groups became more important for social stuff at some point and FB loss significance. This is not for everyone, not everyone is the same.
You could literally replace most comments here, yours included, with "different things for different people". What's the point in bitching about how I DONT GET PEOPLE THAT THINK X!!! well I don't understand how you think either mate.
