[originaltext] Do the names MySpace, Facebook, Orkut, etc. mean something to

Do the names MySpace, Facebook, Orkut, etc. mean something to you? They probably do because they are some of the most popular sites on the Internet today. These sites are all called ’social networking’ sites because they help people meet and discuss things online. Each of these social networking sites has its own strengths: MySpace is especially popular among teenagers, Facebook is popular with college age people, Orkut is especially loved in Brazil, and CyWorld is the site to visit in South Korea. The common thread between all of these social networks is that they provide a place for people to interact, rather than a place to go to read or listen to ’content’.
    Social networks are considered to be web 2. 0. What does this mean? To understand this, it’s important to understand what the original web did (often called web 1.0). Back in the nineties, the Internet was a place to go to read articles, listen to music, get information, etc. Most people didn’t contribute to the sites. They just ’browsed’ the sites and took advantage of the information or resources provided. Of course, some people did create their own sites. However, creating a site was difficult. You needed to know basic HTML. It certainly wasn’t something most people wanted to do as it could take hours to get a basic page just right. Things began to get easier when blogs were introduced. With blogs, many more people began writing ’posts’, as well as commenting on other people’s blogs.
    The key to the success of web 2. 0 companies is relying on users to create content. Besides the social networking sites discussed here, other huge success stories include: Wikipedia, Digg. com and the latest success — Twitter. All of these companies rely on the desire of users to communicate with each other, thereby creating the ’content’ that others want to consume.
