Recode Daily: Twitter is finally in the black after 12 years, and the stock indexes sank even more

The major stock indexes plunged more than 1,000 points yesterday as a sell-off resumed, bringing the index down 10 percent from the record it reached two weeks ago. The market’s turmoil began last Friday and has continued this week as investors worried about early signs of inflation. The market is technically in “correction” territory — a term used to indicate that a downward trend is more severe than simply a few days of bearish trading.

Twitter finally made a profit after nearly 12 years, four of them as a public company. The company reported its first-ever profitable quarter yesterday, making $91 million in Q4 2017. Monthly users grew by 4 percent year over year, but stalled quarter over quarter, staying at 330 million. One quarter of profit, however, barely registers in a long line of losses: Twitter’s cumulative net loss since going public is $2.2 billion; Facebook has made $34 billion. Twitter CEO Jack Dorsey said that average tweet length has remained about the same since the service doubled the 140-character limit in November, and that user engagement has increased.

GrubHub’s stock price skyrocketed to 29 percent yesterday, after the company announced impressive Q4 results — and a giant partnership with the owner of Taco Bell, KFC and Pizza Hut. GrubHub will partner with Yum Brands to offer pickup and delivery options nationwide at thousands of Taco Bell and KFC locations (Pizza Hut already delivers). [Jason Del Rey / Recode]

Facebook is testing a long-demanded “downvote” button with certain users, effectively creating the “dislike” button long predicted by memes and articles since the inception of the “Like” button. The test appeared for several users yesterday in the comments section — it could signal one of the biggest overhauls in years to the social network. [Chelsea Ritschel / The Independent]

Sneakerhead superstore Flight Club has merged with the GOAT sneaker startup, which sells hard-to-find sneaks through a mobile shopping app. The combination will create a hybrid retailer with a valuation of about $250 million. Flight Club’s two stores, in New York City and Los Angeles, will remain under its own name; a few more flagship locations are expected in other major cities in the coming years.

Here’s a scary first-person look at the experience of living in a smart home — and how it creates new streams of personal information that can be used to profile us. One reporter connected as many appliances as she could to the internet — an Amazon Echo, lights, a coffee maker, a baby monitor and even a bed. The other reporter tracked the patterns of data trails generated by the connected devices. [Kashmir Hill and Surya Mattu / Gizmodo]

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
