【推荐1】A homeless man is fast becoming an Internet sensation (引起轰动的人) with his video blog of life on the street of Moscow, it’s reported. Yevgeny Yakut moved to the Russian capital, hoping to live better, but soon found himself one of the many homeless people in the city known for its housing shortage and high cost of living. But he thinks he has found a way out. “I was warming myself in a railway station when I saw a television report on bloggers earning money by making advertisements,” he tells the TV channel Moscow 360. A young passer-by got chatting to him about the idea, and agreed to be Mr. Yakut’s cameraman, using a smart phone to record his friend’s humorous stories of daily struggle to “find food, a place to sleep, and keep out of the way of the police”. So viewers could see how he lives in central Moscow without a home.

They upload the regular videos to YouTube, where Mr Yakut is hoping to attract enough subscribers (订阅者) to interest advertisers in his channel. So far, the pair have attracted more than 18,000 subscribers---around half of those since Russian media began reporting his story and more than 450,000 video views.

In one video Mr Yakut points out free shuttle bus (班车) serves that he, and others in his position, can use to get around. He also shows viewers the best place he has found to wash and shave---a modern shopping centre bathroom---and how to make use of the items other Muscovites have abandoned in the city’s bins.

The popularity of the pair’s You Tube channel has impressed video-marketer Kirill Kalashnikov, who tells Moscow 360 that with some professional help, “this could be turned into a million subscribers within a year”. In the meantime, Mr Yakut says supporters can make donations through a Moscow drain pipe, where he hides his dollars in a deposit box made from a soft-drink bottle.

【推荐3】For better or worse, we might be in the Age of the Group Chat. In a recent survey, most people said they felt stressed out by group messages, which can feel like a part-time job.

Connection is wonderful. Grexts, short for group texts, have the feature of imitating (模仿) the casual back-and-forth of a dialogue, and the result can be more dynamic and fun than a two-person thread. Having a chat going also means you have a space to share your updates throughout the day, a reminder that you’re part of something.

Some researchers call this “ambient (周围的) virtual presence”: Even when you’re alone, you’re not alone. One researcher compares this phenomenon to echolocation (回声定位), the process that some animals, such as bats and dolphins, use to locate objects: They produce a continuous sound and use the resulting echo to sense their surroundings. Humans might use technologies such as group chats in a similar way — as a call-and-response, taking in information about their social networks and locating themselves within those webs.

But taking in too many signals can be overwhelming. Professor Bayer argued that group chats can create a “waterfall type of effect”, where messages keep flooding in and adding up. Eventually, you’re underwater. Another researcher suggested that different chat members all bring their own personalities, communication styles, and expectations for group norms. Without a standard etiquette (礼仪), people have varied opinions about what degree of responsiveness is required — which can cause real tension.

Grext anxiety is hard to resolve because it isn’t just about the group-chat or even mobile technology in general; it’s about the tension between being our own person and being responsible to others. Ultimately, most of us do want connection, even if it involves some duties. A general advice is to give up greats that don’t really interest you.
