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

Bynum called on Yates to apologize.Yates later claimed his comments were taken out of context, particularly in the headlines of some media reports.

Veterinarians are seeing an alarming increase in the number of cases of the canine parvovirus.Nationally, Blue Pearl pet hospitals report a 70 percent increase of the virus compared to statistics collected the previous five years.While an exact reason for the spike has yet to be determined, veterinarians suspect the coronavirus pandemic can shoulder some of the blame.“If people are staying home and have strict stay at home orders, probably vet visits aren’t the first thing on their minds,” said Dr. Lenore Bacek with Blue Pearl. “Financially, some people took a large hit to their normal finances during this time and routine vaccines weren’t a priority.”She added that people may be taking their newly adopted puppies to dog parks before they are fully vaccinated.Parvovirus is highly contagious because it can live on surfaces like grass or blankets for months and years.“Just assume it’s in the environment and don’t take your puppy somewhere other dogs have been,” Dr. Bacek said.Symptoms of the virus include vomiting and diarrhea, fever, abdominal pain, decreased appetite, weakness and weight loss.Dogs can’t pass the virus to humans. However, the increase of parvovirus cases could mean other important vaccines are being neglected.“We worry if they are not getting parvo vaccines, are we missing things like rabies vaccines, which could have a public health implication?” Dr. Bacek said.Puppies are most at risk, but the virus can also impact adult dogs. Veterinarians recommend adults receive a booster vaccine every three years.If a dog falls ill, they can face expensive treatment.“With aggressive treatment, hospitalization, IV fluid therapy, supportive care, the survival rate is high, close to 90 percent,” Dr. Bacek said.However, the financial and emotional toll of a dog getting sick can be avoided with proper vaccines.“We want to make sure as the first wave continues and second waves comes, that vets are seen as an important factor in public health,” Dr. Bacek said.KSTU's John Franchi was first to report this story. 2051
