What’s just as common as presents under the tree this time of year? Why, a family disagreement of course!

Mark Zuckerberg’s sister, Randi, has experienced the feeling of Facebook not being so private even if that is the intent of a post. A picture she shared privately amongst friends (well, that’s at least what she was led to believe) showed up in the Twitter feed of VoxMedia’s director or marketing and projects, Callie Schweitzer. The photo was of a private Zuckerberg family moment.

Other than the fact that there is a bazillionaire smirking in the background the photo is pretty normal. It was, however, deemed to be as private as Randi Zuckerberg’s ability to share it on Facebook made it. And once shared on Twitter by Ms.Schweitzer, well, let’s just say it didn’t appear to make Randi too happy.

Let’s play a game. It’s called Facebook Hide and Seek messaging. In this game, you send me a message through Facebook and then you guess whether or not I’ll ever see it and I guess where it will turn up. Doesn’t that sound like fun?

Here are the rules:

First, I have to choose what kind of filtering I want on my Facebook account.

Basic Filtering is the same as “friends of friends” or “everyone”
Strict Filtering is the same as “friends”

But see that word “mostly” in both choices – that gives Facebook the right to put messages in your Inbox even if they don’t meet the requirement. Facebook says they do this for your own good, for example:

OK, folks. At 11:11 am EST you can rest easy when the world comes to a dramatic end because it looks like Instagram has heard Instagram-nation, has been beaten into submission (which in Internet terms means issuing a mea culpa) and is attempting to make nice (which in this case is going back to the old terms of service that no one likely read in the first place).

Kevin Systrom, co-founder and front facing executive for this whole ‘incident’, issued Instagram’s solution in a post late yesterday. Let’s break the post down and try to translate for us common folk.
