This has been discussed before. The result was that if your plates are visible, its not hard to get your address. Ok, so what? Well... if your car is obviously parked outside your home, thieves know they can show up at night and steal your wheels. Or, if you picture your car in your garage beside your 1965 Corvette Stingray, then, well.. they know where a 1965 Corvette Stingray is parked, etc.

Bottom line is if you are too lazy to blur out the plates, then don't give too much information in the background of the pictures.
