Swarfing does have a valid point though, if the location information is too specific.

As I said previously, it's not unknown for undesirables to use public information to know where to burgle.
On several forums I use, even though I've never met the posters, I could tell you some of the expensive items they own. Take one undesirable, such information, a nice map showing exactly where posters stay, and you'd be aswell leaving the door wide open.
