5. Dorsey is a fan of how Tesla CEO Elon Musk uses Twitter.Musk has run into trouble in the past for what he tweets but Dorsey is a fan of how Musk uses the platform. Last year, for example, Musk was sued by the US Securities and Exchange Commission after he tweeted that he was considering taking Tesla private but later settled the lawsuit. 3. It’s unlikely Twitter will suspend President Donald Trump from the platform.Twitter has faced calls in the past to boot Trump from the platform over allegations that the president violated its rules including against hate speech. But Dorsey noted that Twitter also considers whether tweets are newsworthy or in the public interest. He also declined to say what newsworthy historical public figure he might ban. Always going to experiment with new models. Periscope has super hearts, which allows us to learn about direct contribution. We’d need to figure out the value exchange on subscription. Has to be really high for us to charge directly #karajack— jack (@jack) February 12, 2019 Tags Elon Musk Jack Dorsey Twitter To me personally? I like how @elonmusk uses Twitter. He’s focused on solving existential problems and sharing his thinking openly. I respect that a lot, and all the ups and downs that come with it #karajack— jack (@jack) February 12, 2019 Twitter CEO and co-founder Jack Dorsey. Drew Angerer/Getty Images Twitter CEO and co-founder Jack Dorsey couldn’t stop tweeting on Tuesday. For more than 90 minutes, Dorsey participated in an interview through tweets with Recode’s co-founder Kara Swisher. The 42-year-old tech mogul talked about a variety of topics from tech responsibility and safety to the use of the platform by President Donald Trump and Tesla CEO Elon Musk. He also quipped he would rather be eating Cheez-Its than “bad meat” with Facebook CEO and co-founder Mark Zuckerberg.With Twitter users chiming in every minute, even Dorsey admitted the format of the #Karajack interview was hard to follow. Walt Mossberg, a veteran tech journalist, remarked on Twitter that it was “a living example of how Twitter is a chaotic hellpit.”The chaos highlighted how much work Twitter has to do to make the site easier to use. The social network has been losing users as it tries to crack down on fake accounts, election meddling, harassment and misinformation on the site.Here are six takeaways from Dorsey’s interview:1. When it comes to tech responsibility, Dorsey gives himself a C grade.Tech giants have a lot of responsibility resting on their shoulders, including protecting democracy and the safety of its own users. Swisher asked Dorsey what grade he would give Silicon Valley and himself for tech responsibility. Dorsey, who noted that the platform was prioritizing physical safety first, isn’t exactly giving himself high marks. 2. Twitter knows it has a harassment problem.Twitter has come under fire multiple times for not doing enough to combat harassment on the platform. A study last year even found that the site is a “toxic place” especially for female journalists and politicians. When people take a break from the platform, Dorsey says it doesn’t feel good. Comments 6 Myself? C. We’ve made progress, but it has been scattered and not felt enough. Changing the experience hasn’t been meaningful enough. And we’ve put most of the burden on the victims of abuse (that’s a huge fail). #Karajack— jack (@jack) February 12, 2019 Feels terrible. I want people to walk away from Twitter feeling like they learned something and feeling empowered to some degree. It depresses me when that’s not the general vibe, and inspires me to figure it out. That’s my desire #karajack— jack (@jack) February 12, 2019 6. Twitter still has a lot of work to do to make its site easier to use.When the interview was over, even Dorsey wasn’t giving himself a big pat on the back. He mentioned last week he wanted to do an interview via tweets because it was a feature that Twitter is thinking about building. Clearly, Twitter still has a lot of work to do. Internet Services Tech Industry 4. The bar would have to be high for Twitter to charge users a subscription fee.Twitter said in 2017 that it was exploring the possibility of offering a premium version of the social network for professionals. “Is Twitter still considering a subscription service?” Swisher asked Dorsey. The tech mogul noted the company needs to figure out what value it would get from charging users a fee. Share your voice This thread was hard. But we got to learn a ton to fix it. Need to make this feel a lot more cohesive and easier to follow. Was extremely challenging. Thank you for trying it with me. Know it wasn’t easy. Will consider different formats! #Karajack— jack (@jack) February 12, 2019 We hold all accounts to the same terms of service. The most controversial aspect of our TOS is the newsworthy/public interest clause, the “protection” you mention. That doesn’t extend to all public figures by default, but does speak to global leaders and seeing how they think.— jack (@jack) February 12, 2019 CES 2019: See all of CNET’s coverage of the year’s biggest tech show.Everything about Fortnite: What you need to know about the hit game.
