Facebook places - My thoughts

I've had a facebook account for a good while now but after updating my iPhone version a few days ago I began to think about it's new feature and was a little worried by the "places" feature. It got me thinking that if I'm tagged or my status is shown as me being for example on holiday, then anyone who reads it knows that I'm not at home and therefore leaving my house vunerable to burglars. When facebook first came onto the scene it was new, cool and enjoyable but now I think it's slowly becoming intrusive and too personal.I mean, do I really want everyone to know where I am all the time? No I don't.
