When you post a Status update on Facebook, all your friends see it on their News Feeds, as long as they haven't opted to "Hide" your posts, right?
It's possible to know who's seeing your status updates, right?
Wrong, wrong and wrong!
Based on extensive but unscientific polling of my own "social graph," I've discovered a massive disconnect between what people believe happens on Facebook and what actually happens.
People think "friending" somebody enables them to maintain a social connection via the News Feed. When a friend gets a promotion, tells about their vacation or just expresses disappointment in the Oscar nominations, I'll see it in my News Feed. And they'll see my own posts. "Friending" someone means I see their posts and they see mine. That's what people believe.
And they're wrong.
The truth is that Facebook recently started using secret criteria to decide whether or not you'll maintain this News Feed relationship. If Facebook's software doesn't like your relationship, Facebook stops delivering News Feed messages without telling you.
Those criteria probably involve the frequency with which you message, chat, post, comment or interact with each friend.
Imagine if the Post Office did that! "The once-a-year holiday card means you're really not that close, so we'll just burn the cards without delivering them and without telling anyone."
Imagine if Gmail did that! "Since you hardly ever get e-mail from your mother, we're going to dump any future messages from Mom in the spam folder without telling you."
Imagine if Firefox did that! "You never post comments in the blog you're visiting, so we're going to return an error message saying the web site is no longer in service."
The GoodIn fairness, Facebook "edits" your News Feed to improve the user experience. If you have hundreds of friends and never chose to "Hide" any of them on your News Feed -- and if Facebook didn't block any of the messages -- you probably wouldn't like your News Feed very much. You might be overwhelmed by both the quantity and the irrelevance of the messages pouring in.
Facebook has no doubt learned that the general public (and when you have nearly 600 million users, you are in fact dealing with the most general of publics) is more likely to stop using Facebook than endure the suffering of a News Feed that functions as a fire hose of relationship spam.
Most people don't care enough to learn about the settings, or change them.
For the minority that does care, there's an "Edit Options" link at the bottom of your News Feed. By clicking on it, you get a dialog box that lets you see posts from "All of your friends and pages" OR "friends and pages you interact with most," which is the default setting that uses Facebook's algorithms to Hide some of your friends' posts from you. You're also presented with a complete list of friends, with the option to hide or un-hide each friend manually.
Because Facebook's policy is about improving the user experience, there is no connection between who you Hide and who Hides you. And you have no control over or knowledge about who is blocking your posts whether it's your friends or Facebook.
If Facebook's algorithms are preventing your Status updates from reaching some of your friends, well, there's nothing you can do about that. If a friend posts on your Wall, that may or may not trigger Facebook to un-Hide your updates from that friends' wall. But there's nothing you, personally, can do.
Still, Facebook deserves credit for trying to solve the problem of social information overload in a way that requires no skill or initiative on the part of the user.
It's a hard problem to solve, and Facebook's solution isn't perfect. And it's probably better than doing nothing and simply allowing people to hate Facebook.
The BadWhat's bad about Facebook's approach is that it leaves users in the dark.
Most users don't know any of this is happening. And if they do know it's happening, they don't know how to fix it. And if they do know how to fix it, than cannot know the criteria Facebook uses to block their own updates, nor can they ever know who is seeing their posts.
It's also unknown whether Facebook "grades on a curve." In other words, it's possible that the more "friends" you have, the more aggressively Facebook cuts the connects between News Feeds, based on the belief that you should only have a certain number of friends.
There's no way to know. All of their criteria are secret.
The problem is that Facebook users "friend" people at minimum in order to see each other's Status updates. That Facebook quietly severs these connections without telling users is an unhappy surprise to most people I've revealed this to.
