Too often, many people, especially teenagers don’t think before they post. So they post a thought they think is funny or a photo or a video they feel good about or a reaction to an issue. Within seconds, the whole world can see what they’ve posted. Most of the time, this isn’t a problem—but here are 3 things for teenagers to consider before posting on social media, to help them avoid making a mistake.

1. Who will read it?

Any time we post something, there is potential for that post to go viral(疯传). You need to be clear that there is no privacy on the Internet. You should know that all your friends, teachers, families, and any people you may never meet can (and might) see everything you post.

2.    ▲   

Before posting, you need to consider the people who may read the post or hear about it, not just those to whom you send it directly. Will the post embarrass anyone? Will it hurt someone’s feelings? Will it make someone feel unsafe? 

3. How does it represent you?

We live in a quick-to-judge society. When you post, you are sending out a digital representation of yourself. You need to realize that you will be judged because of your posts. When your posts include pictures or videos, you will be judged on superficial aspects of the posts including how you look, the clothes you wear, and the quality of the pictures or videos. You’ll also be judged on your opinions about social issues as well as whether your posts are funny or interesting.

So, before pushing the button to post, you should take a moment to look over the post and consider whether it’s appropriate. If you aren’t sure, you should probably remember: When in doubt, don’t.
