Why facebook can't be a place to make friends?

First of all you are putting photos of yourself up for anyone to see and say you become friend with a strange guy and then you make a status saying for example "going on holiday for two nights to ...." Then for 1 he then knows ur name and where u will be and second he knows ur house will have know one is home. So obviously it's an unlikely thing to happen but u can't trust everyone and you could end up asking a new friend to meet you somewhere and u turn up and that arnt who that said they were so just stick to the people you actually know
