Twitter’s U.S. midterms hub is a hot mess

Today, Jack Dorsey tweeted a link to his company’s latest gesture toward ongoing political relevance, a U.S. midterms news center collecting “the latest news and top commentary” on the country’s extraordinarily consequential upcoming election. If curated and filtered properly, that could be useful! Imagine. Unfortunately, rife with fake news, the tool is just another of Twitter’s small yet increasingly consequential disasters.

Beyond a promotional tweet from Dorsey, Twitter’s new offering is kind of buried — probably for the best. On desktop it’s a not particularly useful mash of national news reporters, local candidates and assorted unverifiable partisans. As Buzzfeed news details, the tool is swimming with conspiracy theories, including ones involving the migrant caravan. According to his social media posts, the Pittsburgh shooter was at least partially motivated by similar conspiracies, so this is not a good look to say the least.

Why launch a tool like this before performing the most basic cursory scan for the kind of low-quality sources that already have your company in hot water? Why have your chief executive promote it? Why why why

A few hours after Dorsey’s tweet, likely after the prominent callout, the main feed looked a bit tamer than it did at first glance. Subpages for local races appear mostly populated by candidates themselves, while the national feed looks more like an algorithmically generated echo chamber version of my regular Twitter feed, with inexplicably generous helpings of MSNBC pundits and more lefty activists.

For Twitter users already immersed in conspiracies, particularly those that incubate so successfully on the far right, does this feed offer yet another echo chamber disguised as a neutral news source? In spite of its sometimes dubiously left-leanings, my feed is still peppered with tweets from undercover video provocateur James O’Keefe — not exactly a high quality source.

In May, Twitter announced that political candidates would get a special badge, making them stand out from other users and potential imposters. That was useful! Anything that helps Twitter function as a fast news source with light context is a positive step, but unfortunately we haven’t seen a whole lot in this direction.

Social media companies need to stop launching additional amplification tools into the ominous void. No social tech company has yet exhibited a meaningful understanding of the systemic shifts that need to happen — possibly product-rending shifts — to dissuade bad actors and straight up disinformation from spreading like a back-to-school virus. 

Unfortunately, a week before the U.S. midterm elections, Twitter looks as disinterested as ever in the social disease wreaking havoc on its platform, even as users suffer its real-life consequences. Even more unfortunate for any members of its still dedicated, weary userbase, Twitter’s latest wholly avoidable minor catastrophe comes as a surprise to no one.

Facebook shares climb despite weak Q3 user growth and revenue

After last quarter’s bloodbath earnings report that cut 20 percent from Facebook’s share price, the social network stumbled in Q3 2018, reaching 2.27 billion monthly users, up 1.79 percent compared to Q1’s slowest-ever growth rate of just 1.54 percent, compared to an 2.29 billion Wall Street estimate. Daily active users hit 1.49 billion, up 1.36 percent compared to Q1’s 1.44 percent, missing the 1.51 billion estimate.

But the real growth story depends on its core US/Canada and Europe markets where Facebook saw zero growth and lost 1 million users respectively last quarter. In Q3, Facebook added 1 million monthly users to reach 242 million in the US/Canada region, but held flat at 185 million dailies there. It lost 1 million users in Europe in both dailies and monthlies. Those markets make up over 70 percent of its revenue, which is scaring Wall Street.

As for Facebook’s business, the company earned $13.73 in revenue, compared to Refinitiv’s consensus estimate of $13.78 billion, and saw $1.76 EPS compared to an estimate of $1.47, making for a mixed report. Facebook blamed foreign exchange headwings for $159 million in Q3, which was the difference between its miss and a beat on revenue.

Facebook’s share price closed at $146.22 before earnings were released, still massively down from its $217 peak for before it announced user growth troubles and slowing revenue growth in Q2’s earnings report. Facebook shares fell 3 percent upon the announcement of earnings. That’s despite earning $5.14 billion in profit

Facebook hoped to show that its business can keep growing even as it spent massively to double its security and content moderation team from 10,000 to 20,000 this year. It did note that “more than 2.6 billion people now use Facebook, WhatsApp, Instagram, or Messenger each month, and more than 2 billionpeople use at least one of our Family of services every day on average.”

But the company’s revenues and profits have been overshadowed by the non-stop parade of scandals ranging from election interference to its biggest security breach ever. Next quarter we’ll see if the breach scared users away or if Facebook logging them out for safety led some to never log back in.
