Twitter went into an uproar Friday after a BuzzFeed report that the social network was on the brink introducing an algorithmic, more Facebook-style feed. Twitter CEO Jack Dorsey tried to calm fears this morning in a series of tweets, but he did not deny the substance of the report. High-profile users have threatened to abandon the service, and the changes reportedly could arrive as soon as this week. The Verge has now seen the redesigned timeline and can share new details about how it’s going to work.

So, how will your new Twitter timeline look? With the caveat that some things could change in the final shipping version: a lot like the old timeline. Here are a couple of screenshots from a tipster who has been in the test group for several months:

You have to look close to see that the tweets are out of order: in this case, a few tweets from nine or ten hours ago show up before one that was posted two hours ago. But screenshots like these have been floating around for a few months now. What’s really important is how the new timeline works in practice.

Yes, you can opt out

The algorithm that will re-order your timeline is based on the one that ranks tweets for the “while you were away” feature that Twitter introduced a year ago. The best way to think of the new timeline is as an expanded version of this feature. Spend an entire day away from Twitter, and when you open the app again, you’ll see highlights from the day. If you open it up a few times a day, you’ll see a handful of “while you were away”-style sections breaking up the chronological tweets. And whenever you pull down to refresh your stream, it’s back to the regular, reverse-chronological timeline.

Here’s one way to think of it: scroll down through the timeline, and it’s like the Reddit homepage, showing the most popular things first. Scroll back up, and the feed turns into regular reverse-chronology Twitter. One tester told me that the new timeline will also show you related posts for popular tweets if you want to dive deeper. In any case, this will be the new Twitter by default — but you will be allowed to opt out of the new timeline, The Verge has confirmed.

Former Twitter employee Paul Rosania, who was the product manager for the timeline before leaving recently for Slack, mounted an impassioned defense of the re-ordered timeline this afternoon. “In a purely chronological feed, tweet quality is distributed *randomly,*” he wrote. “If you miss any tweets, *any at all,* there will be just as much good stuff in there as there is in what you actually see. Delivering some of that, by pushing down something else, is *guaranteed* to give you a better experience. Not by principle, just by math.” Rosania concluded: “Someday soon, the tweets you see will be a little more interesting, and the tweets you miss won’t be as important. And guess what: You won’t even notice. You won’t! You think you will, but you won’t.”

“It tears conversations apart.”

The Verge spoke to two users who have been testing the new timeline for a few months. Neither particularly liked it. “I started to get used to it but I still think that it is a terrible idea,” Twitter user Robin Bonny told me. “It tears conversations apart, and it’s really confusing when some people have been live-tweeting an event and those things get scattered all across my timeline. It makes it extremely hard to follow events, and destroys one of the core values of Twitter, in my opinion.” Another user, Coady DiBiase, was only slightly more positive. “It’s definitely nice in terms of catching up on things I might’ve missed, but it’s a departure from the core idea of Twitter, so overall it complicates things.”

But both are daily users of the product, and Twitter is in search of product changes that will bring them hundreds of millions of new users. The analyst Ben Thompson wrote recently that an algorithmic timeline has been one of Facebook’s core advantages over Twitter, allowing it continue to grow rapidly as Twitter’s growth slowed. As Bret Taylor, former chief technical officer of Facebook, put it this morning: “Algorithmic feed was always the thing people said they didn’t want but demonstrated they did via every conceivable metric. It’s just better.”

Now we know how Twitter’s algorithmic timeline works — but aside from those who have been testing it, it’s unclear how it will feel. Is it truly the best of Twitter, delivered effortlessly? Or, like Bonny says, does it break up conversations and take other tweets out of context? It does not feel like an overstatement to say Twitter’s future could hinge on the answer.

#FirstCrush A tiny startup made a big splash this week by pledging to deliver a wireless Internet service fast enough to replace your home broadband connection.

Starry is taking on cable broadband with a wireless service that promises to deliver 1 gigabit per second downloads.

Starry, a company based in New York and Boston, on Wednesday unveiled a 1-gigabit Internet service, which will launch with a trial in Boston over the summer. That’s about 10 times faster than the average home Internet connection and speedy enough to let you download a two-hour high-definition movie in 25 seconds.

If the promise holds true, Starry could offer you a viable, potentially superior, alternative to the broadband service provided by your local phone or cable provider. The company believes it can undercut traditional broadband providers because it doesn’t have to dig up streets to install physical lines. It would bring much needed competition and higher speeds. What’s not to like?

It turns out that Starry’s promise may be too good to be true. The service is based on a type of super-high radio frequency that can only travel over short distances and is easily distorted by walls or even rain. While this technology has been used to provide fat Internet pipes to businesses, its technical limitations make it expensive to deploy.

“It’s extremely difficult to deliver a highly reliable, high-speed Internet service using these frequencies to residential customers,” said Towerstream CEO Jeff Thompson. His company specializes in delivering wireless broadband to large buildings using microwave dishes and similar high-frequency radio waves.

But Starry CEO Chet Kanojia, best known for his failed attempt to shake up the broadcast industry by bringing live-streaming TV services to consumers through a company called Aereo, believes he’s found the answer.

“The technologies we’re using have been around for a long time and are dirt cheap,” he said in an interview. “But no one else has stitched them together the way we have.”

Starry’s promise

Starry is taking advantage of technological advances and off-the-shelf components used for Wi-Fi and satellite technology to work around these issues.

The Starry Beam radio will sit on atop a building to capture incoming signals. While a traditional provider installing cable or fiber for broadband might spend $2,500 for every home it hooks up, Starry can do it wirelessly for $25 per home, Kanojia said. That’s thanks to a combination of tricks to amplify and direct the signal. He said the technologies allow him to transmit a signal 1 to 2 kilometers away.

Starry Beam radios will sit on top of buildings to capture the incoming signals. They’re then transmitted to the Starry Point, another box that sits outside of the customer’s window in their house or apartment, which then pipes the signal inside to yet another device called the Starry Wing. Starry Wing then broadcasts the connection throughout the home.

Starry hasn’t offered pricing details on any of these products, but Kanojia said customers will not be responsible for the cost of the devices. Instead, pricing will be bundled into the service.

Dialing the right frequency

That all sounds great, but many are hung up on the airwaves that Starry plans to use.

Radio waves work like this: Higher frequency signals allow you to carry a lot of bandwidth, but at shorter ranges. That means you have to place more radios closer together. Wireless companies prefer to use lower band spectrum because they don’t have to build as many cellular sites and because the signals can go through walls.

Starry is employing radio waves that range between 37 gigahertz and 39 gigahertz utilizing a technology called millimeter wavelength. At that high rate, walls and even heavy rainstorm or foggy mist can cause disruptions. In comparison, many of the US carriers use spectrum in the 700 megahertz band.

Some experts say that Starry is likely using the right technology to overcome technical hurdles, but they’re skeptical the company can deliver the reliable performance at low costs.

Beyond technology, the bigger hurdle will be the cost to deploy the network, said Khurram Sheikh, president of SiBeam, which is working on chips that can tap into millimeter wavelength technology.

It’s all about real estate

One of the biggest expenses will be finding enough rooftops for Starry to build a dense network. While the radios are relatively small and use little power, the company still needs to negotiate deals with building owners for access to rooftops and other places to put the equipment.

“All wireless providers are real estate plays,” Thomson said. “The success of our business depends less on the technology and more on our ability to negotiate great long-term real estate deals.”

Kanojia isn’t too worried. He struck similar deals to get radios up for its Aereo service, which plucked broadcast TV signals and sent them down to its customers.

“That’s just a process you have to go through,” he quipped.

Many in the wireless community, especially those working on 5G, which also plans to use higher frequency radio signals, will be watching Starry closely.

“We like to see others innovating in this area,” Sheikh said. “If a startup shows something real, it will accelerate things and we’ll get more of this technology to market faster.”
