Privacy settings
To allay concerns about privacy, Facebook enables users to choose their own privacy settings and choose who can see specific parts of their profile.The website is free to users, and generates revenue from advertising, such as banner ads.Facebook requires a user's name and profile picture (if applicable) to be accessible by everyone. Users can control who sees other information they have shared, as well as who can find them in searches, through their privacy settings
Comparison with Myspace
The media often compares Facebook to MySpace, but one significant difference between the two Web sites is the level of customization.[69] Another difference is Facebook's requirement that users give their true identity, a demand that MySpace does not make.[70] MySpace allows users to decorate their profiles using HTML and Cascading Style Sheets (CSS), while Facebook allows only plain text.[71] Facebook has a number of features with which users may interact. They include the Wall, a space on every user's profile page that allows friends to post messages for the user to see;[72] Pokes, which allows users to send a virtual "poke" to each other (a notification then tells a user that they have been poked);[73] Photos, where users can upload albums and photos;[74]and Status, which allows users to inform their friends of their whereabouts and actions.[75] Depending on privacy settings, anyone who can see a user's profile can also view that user's Wall. In July 2007, Facebook began allowing users to post attachments to the Wall, whereas the Wall was previously limited to textual content only
