Although I agree that you shouldn't post too many pieces of confidential information on the web, I can't but conclude that this is a typical case of modern day paranoia.

For centuries people didn't care about (snail) mail and to have their address listed in the white pages. Heck, it's even handy, 'cause that old friend of yours might finally trace you and return that $1000.00 he owed you! But nowadays everything is being overshadowed with this "terrorism" thing. It makes me sick, to be honest. The chances you receive an anthraxed letter in the mail is -I guess- still less than the chance you get struck by lightning and so are all the other terrorist-related acts. Please do remember that the world wasn't introduced to terrorism after 9-11. Look at Spain and/or Ireland for example. Terrorism was around for years.

Please, oh please stop this paranoia ... then again, if we don't "the terrorists have won!". If you don't like other monks to know your whereabouts, don't post your GPS info, but please don't post them not because of the potential Indonesian RC plane with explosives...
