1. Social Networking and Elgg

Chapter 1. Social Networking and Elgg

The Web has become social. Is today your birthday? Your family and friends are posting best wishes right now on Facebook. Are you planning to go out for dinner? You are likely checking user reviews of restaurants on a website such as Yelp. Did you read that news article about the latest political scandal? If you did, you may have discussed it with other readers in the comment section of the online news site. The Web has always been a great place to find information, but increasingly people are also using it for social interaction.

With this shift has come a new class of web applications focused on social interactions like those described above. People are sharing and commenting on photos and videos using sites such as Flickr and YouTube. They are updating their "followers" on Twitter about their latest activities. They are using social networking applications such as Facebook to reconnect with old friends, share information about their lives with friends and family, or find people with common interests.
