He sees you when you’re sleeping- He knows when you’re awake!

I was researching Facebook marketing techniques and I came across this really creepy article about how this guy is building all these charts to detect when his Facebook friends are sleeping and when their awake. Just some nerd setting in his apartment looking for something to do and came up with this little bit of code that gathers all this information. Just consider for a moment— If this one guy has these capabilities just think what Big Brother can do with all the information floating around in cyberspace. However it seems to me this code wouldn’t necessarily return a completely accurate report for when your asleep. If you happened to be logged into Facebook and leave your computer on for a week, it looks like it would show you hadn’t slept for a week.
