Twitter CEO Jack Dorsey says "we're ready to question everything" about the social networking site that has been overrun by spam, abuse and misinformation.Dorsey says he and his team are working extensively behind the scenes to stamp out some of the harassment and hate speech that has generated bad headlines lately.But it is a long-term effort, he says, and he is reluctant to commit to an exact timetable for certain changes to Twitter's foundation.In twelve years, "we've changed a lot. But we haven't changed the underlying fundamentals," Dorsey told CNN in an in-depth interview at the company's headquarters on Friday.The basic fundamentals are what he is examining now. For instance: What does Twitter incentivize its users to do?"Every product decision we make is 'telling' them to do something," Dorsey said.So he is thinking about how to help users follow topics and hashtags, not just people."We are aware of some of the silos and how we're isolating people by only giving them crude tools to follow accounts. We need to broaden our thinking and get more back to an interest-based network," he said.Related: Twitter's Jack Dorsey: 'We are not' discriminating against any political viewpointDorsey is also rethinking how follower counts and "likes" on posts are displayed, because the race to gain followers and likes may encourage outrageous behavior.His view is that Twitter needs to be much more "transparent" and open about its actions. But that transparency, some of which was on display during Dorsey's media tour this month, means asking questions without actually answering them.Among the questions Dorsey asked in the CNN interview: "How do we earn peoples' trust?" and "How do we guide people back to healthy conversation?"While he may get credit for asking big, philosophical questions about how his site operates, Dorsey remains vulnerable to criticism about Twitter's inaction.He responded to that by saying "we are taking a lot more action than we ever have in the past." But much of the action is invisible to users, he asserted.For example: The disabling of bot networks and other suspicious accounts. Dorsey said Twitter challenges "10 million accounts every single week to see if they're automations or humans," and takes action accordingly.But Twitter's stock plunged last month when its quarterly earnings report showed a decline in user growth, which the company attributed to its efforts to clean up the site, akin to gardeners removing weeds.Nonetheless, Dorsey is committed to what he calls "conversational health" -- the quality of an exchange on Twitter -- which he is trying to measure with the help of two research groups. He said investors should take a look at the long-term trends: "We see this as necessary and right and we believe in it and we have conviction around it, and we'll take the hit in the short term."Related: Twitter is purging suspicious accounts from your follower countHe also asserted that "over the short term, a lot of this work is invisible, and over the long term, it starts to add up."As for some of the specific changes, like a rethinking of the like button, Dorsey was reluctant to talk about a timeline."We're looking and thinking about all these things right now," he said. So: By the end of the year? "I worry about a time frame like that," he said, "because we also need to take into consideration -- we're a small company. I mean we, in comparison with our peers, we're a small company, but we have this outsized impact and I believe, importance."Later, he added, "We have to understand first the problem we're trying to solve, like what incentives we actually want to drive; not just what we want to remove, but what we want to drive." But he said he knows he wants incentives "that encourage people to talk and to have healthy conversation." 3824

Two nooses were discovered on the grounds of the Mississippi state Capitol on Monday morning, along with signs referring to Tuesday's Senate special election, a state spokesperson said."We are hanging nooses to remind people that times have not changed," reads one of the signs, said Chuck McIntosh, director of communications for the Mississippi Department of Finance and Administration, which oversees the Capitol Police."Tuesday Nov 27th thousands of Mississippians will vote for a senator. We need someone that will respect lynched victims," reads another sign, McIntosh said.CNN affiliate WLBT alerted Capitol Police to the items. An investigation is underway. Officials say they will release pictures of the signs and nooses later Monday.The items were found one day before Republican Sen. Cindy Hyde-Smith faces former Democratic congressman Mike Espy in a Senate race that has drawn attention to the state's history of racist violence.A series of recordings surfaced that featured Hyde-Smith making comments about attending a "public hanging" and suppressing the votes of students in the state.Additionally, Hyde-Smith once promoted a measure that praised a Confederate soldier's effort to "defend his homeland" and pushed a revisionist view of the Civil War, CNN's KFile reported over the weekend.Hyde-Smith accused Democrats of weaponizing the "public hanging" remark and said she would apologize to anyone who was offended by it. 1473

Two days after President Donald Trump’s visit to the city, Democratic nominee Joe Biden met with members of Jacob Blake’s family on Thursday before hosting a community discussion on race.Ben Crump, a civil rights attorney who is representing the Blake family, said that the former vice president met with Blake's family for nearly 90 minutes. Blake joined for part of the conversation via telephone from his hospital bed, both Crump and Biden confirmed.“The family was grateful for the meeting and was very impressed that the Bidens were so engaged and willing to really listen,” Crump said. “Jacob's mother led them all in prayer for Jacob's recovery. They talked about changing the disparate treatment of minorities in police interactions, the impact of selecting Kamala Harris as a Black woman as his running mate. and Vice President Biden's plans for change. Mr. Blake Sr. talked about the need for systemic reform because the excessive use of force by police against minorities has been going on for far too long.”Biden said that Jacob Blake told him “nothing is going to defeat” him."I had an opportunity to spend some time with Jacob [Blake] on the phone. He's out of ICU. We spoke for about 15 minutes. His brother and two sisters, his dad and his mom on the telephone," Biden said.Blake was shot seven times in the back by Officer Rusten Sheskey last month. Sheskey has been placed on administrative leave per police policy.While Sheskey has not been charged with a crime, Biden said earlier this week that charges should be filed.“I do think there's a minimum need to be charged,” Biden said, also adding that the Louisville, Kentucky, officers involved in the death of Breonna Taylor should also be criminally charged.Biden told Kenosha community members that fighting for racial equality “is something worth losing over." He added, "But we're not going to lose."While Biden said that he would make addressing systematic racism a priority if elected in November, Trump said on Tuesday that he does not believe systematic racism is a problem in police/community relations."I don't believe that,” Trump said during his visit to Kenosha on Tuesday. “No, I don't believe that. I think the police do an incredible job. And I think you do have some bad apples. I think you'd agree every once in a while you'll see something. And you do have the other situation too, where they're under this tremendous pressure and they don't handle it well. They call it choking and it happens."Biden promised community members in Kenosha that he would form a policing commission, vowing to invite the police and civil rights leaders to the same table. 2649

Vice President Mike Pence discussed the National Space Council with entrepreneur and inventor Elon Musk during a trip to California last month, a source familiar with the meeting says.The two powwowed at a Los Angeles hotel one evening while the vice president was in the state for a fundraising swing. The conversation focused on the council, which aims to streamline and coordinate national space policy. Pence leads the panel at President Donald Trump's direction.Musk is one of several business leaders exploring private space travel through his company, SpaceX.Musk quit two presidential advisory councils after Trump announced the United States' withdrawal from the Paris climate agreement.Musk tweeted at the time: "Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world."On Friday, the federal government released a congressionally mandated report that found "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases."SpaceX has scored a number of lucrative government contracts in recent years. The company is currently fulfilling a .6 billion contract with NASA to send supplies to the International Space Station. It also has an million contract to send an Air Force satellite into space in 2018.

Uber is adding another transportation option on its app: the electric bike.The new electric motor option called JUMP is just in a few cities right now, but the company hopes to soon make it nationwide.“It's part of a growing mobile effort by Uber to provide all kinds of modes of transportation,” says Dave Nelson, director of operations for JUMP Bikes. “JUMP is an electric, dockless bike that allows you to go further faster and have more fun doing it.”  Similar to electric scooters, the bikes start at ; for every minute after the first, it costs <云转化_句子>.15.Users log into their Uber app in order to request the bike. The app tells you where the bike is located. Once you find your bike, you simply punch in a code and the bike is yours to use.So, what makes Jump bikes different than the motorized transportation options already available?“It is a dockless bike that allows you to pick it up, lock it, drop it off anywhere that's convenient for you,” explains Nelson. “And then, the biggest difference is, that it's electric. It takes you 20 miles per hour and lets you get to where you are going a little quicker.” 1130
