    Millions of people nowadays use Facebook, Instagram and Snapchat to converse with their friends. They use Skype to bridge long distances and Twitter to interact with public figure. But as more of our lives move online, are Internet-based interactions sufficient for a fulfilling life?

There have been considerable warnings about the drawbacks of online interactions. Some scholars have realized that our devotion to the screens is detracting from face-to-face conversations. For instance, a study showed that children who had been spending time with television and computers for a long period of time were significantly worse at recognizing nonverbal（非语言的）psychological suggestions in a conversation than those who had just five days without screens.

But there is another side to the argument: A 2015 Pew Foundation report found that teenagers use online interactions to strengthen their friendships. Plus, 57% of teenagers reported that they’d made friends online. Amori Milkami, a psychology professor at the University of British Columbia, has conducted several studies on online interactions and tells that the nature of online communication is changing as young people treat social networks in an entirely different ways.

Too much research tends to mix all online interactions together, she says, instead of distinguishing between positive, meaning conversations and more superficial, negative exchanges. According to her, online communities can be especially useful for people who have an unusual concern and live in isolated areas, and so are unlikely to meet people with similar concerns in person.

“The major good aspect of online interactions compared to in-person ones is that social network allow users to interact with so many people at once. Whether or not that’s positive or negative depends on the type of friends you have. It’s possible to get the same level of achievement from online interactions as it is from in=person friends,” says Mikami. “This might be hard for older adults to believe and it might not be possible for them, because they might not feel comfortable having those kinds of deep online interactions. To them, the online world will always be more superficial. But young people really see it differently.”

As the nature of online interactions continually evolve, it’s difficult to definitely establish whether or not social media friendships alone are sufficient. But for those who don’t have strong in-person support groups, the value of online communities shouldn’t be dismissed.
