I take the measures I feel I need to to secure my property... I wouldn't go posting those measures in specifics on the internet though. About 3 years ago, someone posted a challenge on THR that felt secure in their online identity, claiming that no one could identify him by starting with the info he had on THR.
Less than 72 hours later, he got a PM containing his name, address, and telephone number. Since then, corporations have become less concerned with securing private information. While technology updates against hacking, its often the hackers that drive the changes. Make your own PERSEC judgment before deciding how much information you want to post on the internet.
