May you please highlight the mistakes in my paper

Why to use Facebook? (I am not sure why he highlighted to)

Have you ever been so bored online that you just stared at the computer screen trying desperately to think of a website to go too. Well, if you make a Facebook account, you will never be bored again, because Facebook offers many things that will keep you interested and stop you from staring at your computer screen.

First, Facebook gives you the opportunity to communicate with your friends no matter where they are. If one of your friends moves to a new state, Facebook allows users to be able to chat with their friends through private messages, chat room, and even wall posts. Have you ever wondered what happened to one of their old high school's friends? Well, with Facebook's popularity growing, it is becoming a site where users can find and communicate with their old friends.

Second, Facebook has some great features. It allows users to upload pictures to an album, which is a great because users are able to show all their pictures to their friends while they are miles away. For instance, if you are on vacation, you can upload your vacation pictures and allow your friends to view them and even make comments about them. Another great feature on Facebook is the games, which include: Mafia War, Family Feud, and Wheel of Fortune. These games are fun to play and highly addicting. (not sure why he highlighted addicting)

Lastly, Facebook is a great way to promote your business and to network. Users can make a page for their business Fans, which is a great way to let people know about their business. For example, if you own a restaurant and would like to get the word out about your new and improved menu, Facebook is a great way to do that. Facebook is also a good place to find a job, because many companies post job openings on Facebook, so if you need a job, you should definitely have a Facebook account.
