Facebook, Twitter, and What a Social Network Owes Its Members
Over the past few days, Topic A on Twitter has been the fatal shooting of unarmed black teenager Mike Brown by police in Ferguson, Missouri, and the ensuing protests and the police response.
For much of that time, Topic B has been “Why hasn’t this been Topic A on Facebook?”
Sociologist Zeynep Tufekci asked that in a post on Medium. Why, she asked, would one social network apparently ignore the biggest topic on another network?
The disparity didn’t last long, she wrote, but what if Twitter’s unfiltered feed hadn’t helped this discussion take off? “Would it ever make it through the algorithmic filtering on Facebook? Maybe, but with no transparency to the decisions, I cannot be sure.”
What feeds your News Feed?
The first thing to know about the Facebook News Feed is that it contains multitudes. Not only do we each get our own individual feed, but the math Facebook uses to prioritize the inevitable information overload is opaque and changes often.
The overriding principle, prioritizing “posts from friends, Pages and groups you interact with the most, as well as other popular stories,” leaves Facebook great flexibility to rank different interactions (does a share outrank a like?) and to define “popular.”
If you post something on Facebook that its formulas deem unworthy of friends’ feeds, you will know that only from a lack of feedback.
But there is a way to get more direct feedback: If you create a public page separate from your personal profile, Facebook will say exactly how many people saw its updates.
I’ve had such a page since 2009, and my posts there usually get to a low fraction of the almost 2,500 who like the page. But a question I posted Sunday night about the prominence of Ferguson news in readers’ feeds, using the trending #Ferguson hashtag, reached 162,048 people in 12 hours.
Maybe Ferguson is now as popular a topic on Facebook as on Twitter? Maybe I should use hashtags more? Maybe this was luck? I don’t know. And people with far larger Facebook audiences than mine seem as confused.
Perhaps Facebook isn’t the best place for discussing hard news. One St. Louis-area journalist who has essentially turned her Twitter feed over to #Ferguson, Staci D. Kramer, noted in an email that while she’d seen Ferguson comments “from fewer than 10 percent” of her Facebook friends, she had been part of that trend.
“I’ve barely posted anything on FB about Ferguson; instead sticking to more personal things,” she wrote. “I think of Twitter first for breaking news.”
Twitter policy changes: Don’t tell, don’t ask
At Twitter, there’s no mystery about what fills your timeline; advertisers’ promoted tweets aside, it’s a reverse-chronological list of what people you follow tweeted and retweeted.
But while Twitter doesn’t make its members decode any mystery math, it can annoy them by changing its rules without explanation.
Last December, for instance, Twitter weakened its block function, the option to lock an abusive tweeter out of most interaction with your account, in a way that would let a harasser continue to abuse people in front of their friends. After a few hours of outrage, Twitter restored the old policy.
Then, a few days ago, some Twitter members started seeing some tweets that had only been favorited, not retweeted, by people they follow. That’s a major change to feature many of us employ as a polite form of acknowledgement.
