The trouble with these social media experiments, of course, is that they are performative and individualistic. There’s an element of commodification: the encounter must be ripe for digital packaging. Often it’s not clear if the filming is consensual. The connections are one-way and border on the exploitative or manipulative. They are designed for individual personal growth or free, self-directed therapy (“this made me more confident”) and for clicks and voyeurism (“check out this person’s reaction”). The effect is to make “talking to absolutely anyone” seem even more alienating, fake and narcissistic. This has spawned a secondary genre of parody videos such as the comedian Al Nash’s “A cup of tea with a stranger – an amazing conversation!” In this clip, an irritating interviewer passes tea to a stranger on a park bench under the guise of “helping you with your loneliness”, only for the encounter to turn awkward when the stranger accidentally drops the cup and smashes it.

“以前跑旧线，有些弯道或道口，速度得压到每小时50公里。”火车司机顺迪说，“现在新线基本不用减速，能稳稳跑在100公里左右，准点率高了，乘客体验也舒服多了。”他拍了拍驾驶台：“这台机车是从中国进口的，动力足、稳定性好。我真希望以后能有更多中国造的机车和车厢，更盼着泰中高铁早点通车，让泰国真正迈入高铁时代。”，详情可参考新收录的资料

因此，平台往往会追求 “流量最大化、变现效率最大化”，而这种诉求，又造成了算法的功利性，算法根据用户的浏览历史、消费习惯，持续推送其感兴趣的带货视频，形成“信息茧房”，让用户难以接触到其他同类产品的信息，无法进行理性对比，从而提升下单转化率。
