I edited it for you:

A social networking site is how several people make new friends and talk to current friends that also have an account on the website. To be able to use a social networking you are required to create an account. This includes your personal details, such as your name, age and address. Also, a social networking site asks you to have a profile picture. Most people use a picture of themselves, but other sensible people just use a picture of a cartoon or an object/animal they like.

There are lots of risks to social networking, but many people don’t think of these and only recognize the benefits. There are lots of popular social networking sites, such as Facebook and twitter. There are a few different types of social networking sites like discussion sites, general social networking, games with type chat bars next to them, and games with voice chat.

Facebook is an example of a general social networking site. It was first created by Mark Zuckerberg. The idea first came to him when his girlfriend dumped him in Harvard University. He was mad so he decided to create a virus to hack into the library and collect photos of everyone in the school. He then used these pictures to create a website called Face match. Face match was a site for people in the university to use. There were pictures that would pop up and they would have had to give their opinion on their favourite. This then spread to different Universities and a man asked Zuckerberg to take the website and create a new level. He wanted to create a social networking site for people at the universities to message each other, say what they are doing, and to ask others to go on dates. This site grew bigger and into a public site. After a few years it became international and it now extremely popular.

One of the main issues of social networking is bullying.
