Twitter seeks help measuring 'health' of its world
San Francisco (AFP) March 1, 2018 - Twitter on Thursday asked for outside help assessing the health of its world of rapid-fire commentary in the hope of finding cures for trolls, bots, echo chambers and other ills.

Pressure has been building on Twitter -- as well as Facebook and Google -- to prevent malicious uses of the online platform ranging from harassment to spreading hoaxes and manipulating elections.

"We have witnessed abuse, harassment, troll armies, manipulation through bots and human-coordination, misinformation campaigns, and increasingly divisive echo chambers," Twitter co-founder and chief executive Jack Dorsey said in a thread of tweets Thursday.

"We aren't proud of how people have taken advantage of our service, or our inability to address it fast enough."

A Twitter statement said the social network wants "to partner with outside experts" to get a sense of the health of the Twittersphere by measuring the impact of abuse, spam and manipulation.

The move is the latest by Twitter aimed at curbing disinformation, propaganda and provocation.

Last month, the San Francisco-based one-to-many messaging service launched a crackdown on accounts powered by software "bots" which can artificially amplify a person or cause and which have been accused of manipulating the social network during the 2016 US election.

Twitter said the move was intended to rid the service of spam-spewing automated accounts, and not aimed at people using the service according to the rules.

Since the election, Twitter and others discovered how "bots" had been used to sow political divisions and spread hoaxes.

While Twitter tactics have mostly involved removing content violating its terms of use, it has been accused of "apathy, censorship, political bias, and optimizing for our business and share price instead of the concerns of society," Dorsey maintained.

"This is not who we are, or who we ever want to be," he said.

Twitter is asking outside experts to pitch proposals for ways to measure the service's health by the quality of debates, conversations, and critical thinking.

"We simply can't and don't want to do this alone," Dorsey said.

Twitter asked proposals to be submitted by April 13, promising to fund any that are selected in a process expected to take a couple of months.

"If you want to improve something, you have to be able to measure it," Dorsey said.

Facebook remains the most popular social network among Americans but faces a growing challenge from Snapchat for young audiences, a survey showed Thursday.

The Pew Research Center survey showed Facebook holding the dominant platform with 68 percent of Americans using the world's biggest social network.

While Facebook leads the other social networks in all age groups, the gap has narrowed in the key 18-24 segment, where 78 percent use Snapchat compared with 80 percent for Facebook, Pew researchers found.

Facebook-owned Instagram, which emphasizes pictures and video, is also popular with some 71 percent of that age segment, Pew found.

The study is the latest highlighting Facebook's challenge of keeping its core youth audience, while adding older users, amid growth in newer social networks like Snapchat, known for its disappearing messages and media snippets.

"As was true in previous years, Facebook remains the entry point to the world of social media for a majority of Americans," said Pew research associate director Aaron Smith.

"At the same time, Americans today utilize a diverse range of online social platforms in addition to Facebook. And this is especially true of the youngest adults, many of whom have fully incorporated platforms such as Snapchat and Instagram into their social media diets."

Pew found the median American uses three social platforms with considerable overlap among Facebook, Instagram and Snapchat.

Twitter, meanwhile, continues to lag other platforms with 24 percent of Americans using the short messaging service.

Twitter recently reported its first-ever quarterly profit even though its global user base remained unchanged at 330 million compared with more than two billion for Facebook.

Pew said YouTube, which it does not consider a social network even though it has "social elements," is used by 73 percent of US adults.

The report is based on a survey via mobile or landline telephone of 2,002 US adults from January 3-10 with a margin of error estimated a 2.4 percentage points for the full sample.

Two weeks ago, a report by eMarketer said Facebook is losing youths at a faster-than-expected pace and that many are turning to Snapchat.

Facebook has launched a Messenger Kids application for users under 12, with parental controls, saying many children already use messaging applications on their own.

Snapchat has faced problems of its own recently amid complaints about an application redesign which separates friends and media content, with a tweet from reality star Kylie Jenner causing a stock plunge.

Sensors help smartphones keep eye on solo seniors
Barcelona (AFP) Feb 28, 2018
Looking after an elderly relative who lives alone can be a huge source of worry. But what if your smartphone could automatically alert you if your mother has stayed in bed all morning or suffered a fall? Small sensors that monitor home activity and can send alerts to smartphones are marking it easier to keep an eye on seniors from a distance, helping them to live independently for longer instead of going to a nursing home.
