Facebook revela até onde seus amigos estão
Coleira eletrônica ganhou o apelido de 'Amigos Próximos'
O Facebook anunciou nesta quinta-feira um novo recurso que, quando habilitado, permite receber notificações de amigos que estão em locais próximos. Chamado de 'Amigos Próximos', ele mostra aos amigos a localização aproximada do usuário, e vice-versa, além de compartilhar a localização exata por um período limitado de tempo. O recurso será integrado ao app do Facebook para iOS e Android nas próximas semanas.
O novo recurso foi desenvolvido pela equipe do Glancee, startup que criou um app para compartilhar geolocalização e foi adquirida pelo Facebook em 2012. Com a integração da tecnologia ao Facebook, os usuários do iPhone e Android poderão ver uma lista de amigos na mesma região. Quando estiverem a uma distância pequena de um deles, o usuário verá a localização exata da pessoa em um mapa por meio do aplicativo do Facebook.
O localizador não funciona se o usuário não habilitá-lo por meio das configurações. Isso significa que, se o usuário ignorar o novo recurso, sua localização não será compartilhada com ninguém por meio da rede social. Da mesma forma, o usuário não receberá notificações sobre a localização de seus amigos, quando eles estiverem em algum lugar próximo. É possível selecionar apenas um grupo de amigos para compartilhar a localização.
A ferramenta ‘Amigos Próximos’ também permite que o usuário acompanhe a localização de amigos que estão viajando, por meio da página do perfil. Isso significa que, ao ver o amigo em um determinado bairro da cidade que está visitando, possa enviar sugestões de lugares para conhecer, em tempo real. O novo recurso exige que o GPS fique ligado o tempo todo, o que pode fazer a bateria do smartphone acabar mais rápido.

Facebook to Notify Users When Friends are NearbyBy Reed Albergotti
Facebook users will soon be able to receive notices on their mobile app when they’re near friends, signaling an effort by the online social network to play a bigger role in real-world interactions.
Users will have to opt in separately to the feature, called “Nearby Friends,” and agree to give Facebook permission to track them at all times, even when not logged into Facebook.
Facebook said it will introduce the service gradually in coming weeks. Users of Facebook’s mobile app will get notifications prompting them to opt in.
Some privacy advocates expressed concerns about the implications for users of opting into the service.
Chris Conley, a policy attorney with the American Civil Liberties Union of Northern California, said Facebook should keep users “regularly aware” of everyone with whom they’re sharing location. Jeffrey Chester, executive director of the Center for Digital Democracy, called on the Federal Trade Commission to review the product.
A Facebook spokeswoman said users will receive regular reminders about Nearby Friends, and that the company regularly discusses its products and features with the FTC and other regulators.
With the new feature, Facebook is entering an already crowded space occupied by the likes of casual dating app Tinder and social check-in service Foursquare. Radar, a smartphone app released last year, tells users where their Facebook friends are. Cloak, on the other hand, uses Foursquare and Instagram to locate friends – and help people avoid them.
Rival social network Twitter in December tested a feature that allowed users to see tweets from nearby, whether or not the user followed the tweeter.
Facebook briefly tested a feature similar to Nearby Friends in June 2012, but quickly stopped after news reports of the test surfaced. At the time, Facebook said the effort was an experiment.
This time, Facebook is hoping to do better by leveraging its more than one billion users. Nearby Friends grew out of Facebook’s 2012 acquisition of mobile app Glancee.
Andrea Vaccari, Glancee’s former chief executive, said developing Nearby Friends posed two technological hurdles: making sure the Facebook app didn’t overwhelm users with too many notifications or drain the phone’s battery.
Because Facebook users tend to be “friends” with co-workers and family members, Vaccari didn’t want users blasted with notifications every time someone arrived at home or the office. Vaccari’s team developed algorithms so that Facebook could learn about its users’ relationships and limit notifications.
Vaccari said his team also figured out how to track users’ locations without draining the battery. “There’s no extra battery drain,” he said.
The notices won’t disclose a user’s precise location, only their neighborhood. Users can then choose to share their exact location with individual friends who are nearby. Vaccari says that feature comes in handy when meeting people in crowded places, like a concert or parade.
Vaccari said Facebook deliberated about whether to show friends’ locations on a map, but decided against it because some users might have viewed it as an invasion of privacy.
Facebook employees have been testing the app in recent months, and Vaccari said it’s already had some serendipitous outcomes. On one occasion, two employees arrived at the San Francisco airport at the same time from different parts of the world. They learned from Nearby Friends that they were both at the airport and the shared a cab home, saving money.
On another occasion, two Facebook employees learned they were vacationing at the same Lake Tahoe resort, and skied together.
Vaccari said the new feature could help Facebook users develop new relationships. He said he developed Glancee because he found himself in new places where he knew few people. He “fell in love with the problem” of trying to meet new friends, he said.

‘Mark Zuckerberg’ Sees a Therapist in WeChat Ad
An advertisement posted this month on a YouTube account that promotes WeChat in South Africa makes fun of Facebook founder Mark Zuckerberg, suggesting that if he wants to make real friends, he’d be better off using WeChat, a rival mobile messaging program owned by Chinese Internet conglomerate Tencent Holdings.
In the commercial, a character named Mark, sporting tousled curly hair that looks an awful lot like Zuckerberg’s, whines to a therapist, saying “I mean, I invented the social network, and now my friends, they’re unfriending me.”
In a German-accented response, the therapist tells Mark to use WeChat’s location-based friend radar function, which he says will help him find “real friends.” Unconsoled, Mark responds to this advice by breaking into tears, prompting the therapist to respond, “Ah, come on, Mark, don’t make me unfriend you too.”
In a second video also posted to the site, the same German therapist is confronted by lawyers sent by “Mark,” who’ve apparently been dispatched to stop him from prescribing WeChat to help his patients. “Oh Mark, your anger is merely a cry for help,” the therapist replies. “Don’t worry,” he says. “With WeChat animated stickers, you can find a way to express your emotions.
Last year Tencent said it would spend as much as $200 million to promote WeChat outside China, and this year, the company signaled that it will continue to spend to market WeChat. Tencent once tried to acquire WhatsApp, according to people familiar with the matter, but the venture failed.
In South Africa, WeChat continues to trail WhatsApp, ranking as the sixth and eighth most popular apps on iPhone and Android phones, respectively, compared to WeChat, which tops both lists, according to research firm App Annie’s mobile app tracker.
An ad targeting Mr. Zuckerberg could help users distinguish between the two apps, which in the past have been confused by users. According to Arthur Goldstuck, managing director of South African technology research company World Wide Worx, when WeChat launched in South Africa in February 2013, many potential users got confused and accidentally downloaded rival WhatsApp instead.
“Our understanding is that WhatsApp downloads grew by 50% in the two months after WeChat was launched here…indicating that there is confusion between the two,” Mr. Goldstuck said.
In an interview last year, Brett Loubser, who heads WeChat’s marketing in South Africa, said that he’d heard about users being confused about the difference between WhatsApp and WeChat. “It’s an extremely competitive environment,” he said. “Obviously the dream is to be number one.”
Asked to comment, Tencent said Thursday it was investigating whether the ad was in fact theirs.
Take-no-prisoner efforts to build market share are normal in China’s Internet sector. Chief executives bicker publicly on social media, and companies run smear campaigns against each other, reaching levels of public antagonism less common outside of China.
