UK Female Musicians, ByteDance, Facebook, More: Tuesday Mid-Afternoon ResearchBuzz, March 3, 2020

NEW RESOURCES

BBC: The database that means festivals have ‘no excuses’ on gender balance. “Festivals hoping to achieve gender balance on their line-ups have been given a major helping hand – in the form of a massive spreadsheet. The document lists every female artist signed to a record label or releasing music independently in the UK.”

TWEAKS AND UPDATES

ChinaTechCity: TikTok maker ByteDance has a search app in China. “Without Google, China’s dominant search engine is Baidu with nearly two-thirds of the market. Now ByteDance, the owner of the viral short video app TikTok, wants a piece of the pie. The company is quietly testing a new search app that’s available for download on some Chinese Android app stores.”

The Next Web: You can now post Facebook’s trippy 3D photos without Portrait mode. “Facebook‘s trippy 3D photos are about to become much more accessible. The company first introduced the feature back in 2018, using depth data from your phone’s portrait mode to provide a nifty parallax effect to your images. It helped make images pop while scrolling through your news feed, and though it’s something of a gimmick, it’s still pretty cool. Problem was, it only worked if you’d activated portrait mode for that particular image.”

USEFUL STUFF

PopSugar: The Remini Photo App Makes Photos Look So Beautiful and Clear. “People have been taking to TikTok recently to flaunt the capabilities of the photo app Remini because of how well it enhances your pictures (old photos especially, the ones that are soft and fuzzy). The app gives photos new life by filling in faces and making photos look new.”

Search Engine Journal: Zero-Click Searches: How to Get Back Your Lost Google Traffic. “More than 50% of Google searches end without an organic click – and that’s a huge threat to our websites. These zero-click searches are resulting in growing losses in both revenue and leads, making Google everyone’s competitor.”

AROUND THE SEARCH AND SOCIAL MEDIA WORLD

ProPublica: Kentucky’s $1.5 Billion Information Highway to Nowhere. “The internet arrived in some parts of eastern Kentucky’s Jackson and Owsley counties on the back of a mule named Old Bub. Nine years ago, Old Bub trudged between the rugged counties’ most remote utility poles, hauling the high-capacity fiber-optic cable intended to help bring Appalachian residents into the information age. Today, Old Bub symbolizes something else — a poor state plodding along the information highway.”

Columbia Journalism Review: Preserving a ‘national memory’ of an outbreak. “The project has become a tribute to the Chinese documentarians who’ve tactfully recorded the complex and often murky realities of life during the coronavirus outbreak amid threats of censorship. In the first weeks of coronavirus news coverage, Chinese news outlets published deep dives and government investigations, reporting on conditions in Wuhan under lockdown that many international organizations could not access. Their published stories are a win for press freedom in a country where the information flow is often strictly supervised.”

Washington Post: Millions of tweets peddled conspiracy theories about coronavirus in other countries, an unpublished U.S. report says. “Roughly 2 million tweets peddled conspiracy theories about the coronavirus over the three-week period when the outbreak began to spread outside China, according to an unreleased report from an arm of the State Department, raising fresh fears about Silicon Valley’s preparedness to combat a surge of dangerous disinformation online.”

RESEARCH & OPINION

Route Fifty: Report: Two-Thirds of Counties Average Internet Speeds Slower Than Broadband. “New data, crowdsourced from an app that tests internet connectivity speeds, found that 65% of counties across the United States are averaging connection speeds slower than the FCC’s definition of broadband.”

ScienceBlog: Tune In To Social Media And Tone Down Your Risk Of Skin Cancer. “Social media smarts could make you less susceptible to skin cancer as new research shows that media literacy skills can help change people’s attitudes about what is believed to be the ‘tanned ideal’.” Good afternoon, Internet…
