Calm, not chaos: How Slack is revamping its sidebar

People have been complaining about Slack’s chaotic notifications for years. Slack says the root of the problem is its sidebar.

What if instead of your standard stack of threads, channels and DMs, Slack presented you with one urgent message at a time? You would address each message in order of importance, never having to switch contexts. This hypothetical version of Slack, head of Design Ethan Eismann explained, would be “infinitely intelligent,” understanding exactly what information you need to see next.

Slack isn’t quite there yet, and it’s unclear if it ever will be. Infinite intelligence isn’t exactly easy. For now, Slack’s product and design teams have done the next best thing when it comes to simplicity: They’ve revamped the sidebar. The changes are subtle: spacing out text, changing the default notification color from red to white, removing unnecessary icons. But VP of Product Ali Rayl hopes that together, they’ll address the most common criticism levied at Slack: overwhelm.

“What have we done with the visual presentation of Slack activity that's making people stressed out?” Rayl asked. “How can we change that visual presentation to just lower the temperature a little bit?”

The heart of the problem is our always-on work culture, a problem that only got worse for some with remote work blending together our homes and the office. Humans, not Slack, are the ones sending a cacophony of messages. We pressure ourselves to respond immediately, even when we don’t need to. “The obligation that we feel to one another is stronger than their immediate need for us in those cases,” Rayl said.

Still, the norms of instant messaging don’t help: “Instant” is literally in the name. The expectation for urgent, immediate responses is “baked into that particular medium in a way that it was never baked into email,” said Slack user and engineering manager Mykola Bilokonsky. To combat this, as well as customers’ general complaints about Slack sending them too many notifications, Rayl said Slack’s leaders first focused on features like “Do Not Disturb” and customizable statuses. But the feedback didn’t change.

“We went deeper,” Rayl said. “We were like, ‘What do you mean when you say notifications?’ And they said, ‘Oh, man, it's the sidebar. It's the badges and it's all bold, and there are all these channels. That’s how we ended up here.’”

It’s not solely about the presence of notifications: It’s about their presentation. Eismann said every pixel within Slack corresponds to a number of “cognitive calories,” or the brain power that helps us interpret our computer screens. Removing icons and streamlining context menus help reduce the cognitive calories Slack requires. For example, “Slack Connect” channels (channels with external partners) used to have a special icon differentiating them. But Rayl said some customers actually had no idea what the icon meant, creating confusion. Now, Slack users can hover over a channel to get a text-based description.

Slack overwhelm affects neurodivergent people more acutely, Bilokonsky said. Bilokonsky, who is autistic and has ADHD, said Slack is “a nightmare for ND brains.” It’s difficult for him to shift contexts, and the incessant pace of notifications can heighten anxiety. Bilokonsky mostly just finds Slack annoying, but some of his neurodivergent friends find Slack’s presence debilitating.

“I’ve got friends who just cannot have Slack open while they’re working,” Bilokonsky said. “The possibility of being distracted in that way makes it impossible for them to allocate their attention on their work.”

Yet Slack is absolutely necessary for Bilokonsky’s job. He has found certain features indispensable, like grouping channels by priority and integrating all of his other tools within Slack. And he appreciates Slack’s commitment to improving its app design, noting that even little changes can make a difference.

“Our computer screens are our environment, to an extent,” Bilokonsky said. “Just like subtle variations in carpet color or wall decoration can really make or break a space, I think stylistic changes can make huge impacts on how it feels to use the app.”

Some people might have trouble pinpointing what design change would improve their user experience. This isn’t the case with autistic people, Bilokonsky said. “We know what we need; we’re screaming it from the rooftops,” Bilokonsky said. “Taking the time to create that feedback channel is awesome.”

Rayl said Slack’s team had accessibility in mind throughout the research process, consulting with neurodivergent and blind customers. It’s also made changes to the sidebar technology supporting screen readers which simplifies the text that’s read aloud.

Company leaders are bracing themselves for feedback. “I'm extremely cognizant of the fact that we are touching the most sensitive spot of the product right now,” Rayl said. But she’s hopeful that after a few days, people will find that the new sidebar has seamlessly improved their Slack experience.

Slack will start rolling out the new sidebar to people on Wednesday, but it will take a few weeks to reach everyone’s Slack accounts.


New Jersey could become an ocean energy hub

A first-in-the-nation bill would support wave and tidal energy as a way to meet the Garden State's climate goals.

Technological challenges mean wave and tidal power remain generally more expensive than their other renewable counterparts. But government support could help spur more innovation that brings down cost.

Move over, solar and wind. There’s a new kid on the renewable energy block: waves and tides.

Harnessing the ocean’s power is still in its early stages, but the industry is poised for a big legislative boost, with the potential for real investment down the line.

Every day, millions of us press the “order” button on our favorite coffee store's mobile application: Our chosen brew will be on the counter when we arrive. It’s a personalized, seamless experience that we have all come to expect. What we don’t know is what’s happening behind the scenes. The mobile application is sourcing data from a database that stores information about each customer and what their favorite coffee drinks are. It is also leveraging event-streaming data in real time to ensure the ingredients for your personal coffee are in supply at your local store.

Applications like this power our daily lives, and if they can’t access massive amounts of data stored in a database as well as stream data “in motion” instantaneously, you — and millions of customers — won’t have these in-the-moment experiences.

Debt fueled crypto mining’s boom — and now, its bust

Leverage helped mining operations expand as they borrowed against their hardware or the crypto it generated.

Dropping crypto prices have upended the economics of mining.

As bitcoin boomed, crypto mining seemed almost like printing money. But in reality, miners have always had to juggle the cost of hardware, electricity and operations against the tokens their work yielded. Often miners held onto their crypto, betting it would appreciate, or borrowed against it to buy more mining rigs. Now all those bills are coming due: The industry has accumulated as much as $4 billion in debt, according to some estimates.

The crypto boom encouraged excess. “The approach was get rich quick, build it big, build it fast, use leverage. Do it now,” said Andrew Webber, founder and CEO at crypto mining service provider Digital Power Optimization.

How lax social media policies help fuel a prescription drug boom

Prescription drug ads are all over TikTok, Facebook and Instagram. As the potential harms become clear, why haven’t the companies updated their advertising policies?

Even as providers like Cerebral draw federal attention, Meta’s and TikTok’s advertising policies still allow telehealth providers to turbocharge their marketing efforts.

In the United States, prescription drug advertisements are as commonplace as drive-thru lanes and Pete Davidson relationship updates. We’re told every day — often multiple times a day — to ask our doctor if some new medication is right for us. Saturday Night Live has for decades parodied the breathless parade of side effect warnings tacked onto drug commercials. Here in New York, even our subway swipes are subsidized by advertisements that deliver the good news: We can last longer in bed and keep our hair, if only we turn to the latest VC-backed telehealth service.

The U.S. is almost alone in embracing direct-to-consumer prescription drug advertisements. Nations as disparate as Saudi Arabia, France and China all find common ground in banning such ads. In fact, of all developed nations, only New Zealand joins the U.S. in giving pharmaceutical companies a direct line to consumers.
