CNN分析几款常用App的功能

For years， it felt like the social media landscape didn’t change much. CNN broke down some of the biggest and buzziest（活跃的） social media platforms—how they work， who they’re for and who runs them.

Facebook… when you’re looking for community （or used furniture）

With more than 2 billion daily users around the world， it’s tricky to describe the stereotypical（典型的） Facebook user. Some come for Facebook Marketplace， which lets users buy and sell everything from vintage furniture to used cars. Many others come looking for community—whether that’s photo updates from their great aunt’s bridge night， or online groups dedicated to new parents or people navigating health challenges. But some of those communities have created serious issues， including groups that have spread vaccine misinformation or those that used the platform to help organize the January 6， 2021， US Capitol attack.

Instagram… when you’re looking to feel envious

What started as a photo-sharing app for friends has changed into a place where the goal is apparently to try to make yourself look more fun and more well-traveled than everyone else. Whether you’re looking at “lifestyle” tips from influencers， sponsored fashion or photos from your high school crush’s summer Italy trip—it’s all there. That culture can make the platform fun and inspirational， but it’s also raised concerns about the app’s impact on users’ mental health， especially for young girls.

TikTok… when you’re looking for entertainment

TikTok is no longer just an app for dancing teens， but many people still scroll （and scroll， and scroll） the shortform video app when they’re looking to be entertained. The platform serves up zippy videos on everything from news and book recommendations to comedy and “get ready with me” style makeup tutorials（教程）， and sometimes content about conspiracy theories.

YouTube… when you’re looking for something to watch

The original video-based social network. YouTube has in recent years worked to crack down on various forms of misinformation. The platform is now trying to take on TikTok with its “YouTube Shorts” short video feature.
