Canada's privacy commissioner has repeatedly expressed concerns about Facebook's policies and in January announced more investigations into the website's practices.
Recently Facebook CEO Mark Zuckerberg said he thinks he's finally found a solution to the privacy issues, and the company has made it simpler to control what you share on Facebook and choose whether to share information with everyone, friends of friends or only friends.
Problem is this new privacy setting initially sets most everyone up with an open account, and unless they change it, it stays that way.
Facebook has evolved a great deal since it was created by a group of university students in a dorm room more than six years ago.
When it hit my university in 2005, it took me a while to join (I was still haunted by the overwhelming feeling I got when too many people started talking at once on my MSN Messenger server), but I eventually caved, just like most everyone I know.
There are the few steadfast Facebook opponents who say they have no use for the thing, so, annoyingly, you actually have to call and invite them to the party instead of merely relying on your post.
But in reality, everyone knows the dangers of Facebook. You wake up the morning after a party and check your profile - there's the proof to show just how ridiculous the night actually was.
And with iPhones and Blackberries more common than mountain bikes in Squamish, events are documented and posted before they're even done.
"You've all made Facebook what it is today," said Zuckerberg.
Yikes.
If you've recently gone to your Facebook account and found it asking whether you want to become an official fan of everything you've listed as interests - from favourite movies to schools and universities you attended.
So you choose a few, and bypass the rest. Now you might want to go check your own privacy settings.
Anyone who agreed to become a fan of their listed likes and interests has their privacy setting changed to allow anyone searching your name to see your name, profile picture, eight of your friends and your favourite music, favourite books, favourite television shows and much more.
So if you are concerned, make sure to visit the new privacy settings on the top right hand corner of your page and unclick the allow button that allows anyone who plugs in your name worldwide to reach your "limited" Facebook page.
Or perhaps use a little discretion and keep those photos of you double fisting margaritas during your last Mexican vacation somewhere only real friends can see them.
