Beyond Email: Likes, Comments, and Sharing

Lesson 8: Likes, Comments, and Sharing

One of the great things about the Internet today is that anyone can join the conversation. Instead of just reading webpages, you can engage and share things you find with your friends.

Whether you're reading a news article, watching a YouTube video, or shopping for a great deal, there's a good chance you'll be able to add a comment or use a social plug-in to post it to your social networks.

Leaving feedback with social plug-ins

If you're viewing something online, you may notice buttons with the Facebook or Twitter logos. These are called social plug-ins, and they're designed to let you give feedback on a webpage. When you Like, recommend, or tweet a website, a link to that page will be posted on your profile, allowing you to share that site with all of your friends at the same time.

While Facebook and Twitter tend to be the most common social plug-ins, there are many others you can use. There is often a "Share" button you can click to see more options. Depending on the website, you may be able to share content in the following ways:

  • Reddit allows you to post and vote for websites you like, which is similar to Liking a page on Facebook.
  • Some sites have a +1 button, which is similar to the Like button.
  • You can pin a link on a Pinterest board.
  • You can email an article or link to someone.

Sharing and comments

People use comments to give feedback, ask questions, or simply continue the conversation. Comments sections often appear at the bottom of a page or article. Not all webpages have comments, but they're especially common on blogs, news sites, video sites like YouTube, and image hosting sites like Flickr.

When viewing or posting comments, be aware that some people intentionally try to start arguments (often called flame wars) by posting outrageous or offensive comments. These people are known as trolls or cyberbullies. While it may be tempting to respond to these comments, it's usually best to ignore them.

  • Interacting with the things you see on the Web provides a better online experience than simply reading webpages.
  • You can easily provide feedback on a page by telling the author what you think or adding information that may be useful to other people.
  • When you find something you like, you can share it with your friends, whether it's a product, article, video, or other website.


  • Trolls and cyberbullies may add negative or offensive comments.
  • Things you post may become permanent, so you have to be careful not to post things that could harm your reputation in the future.
