Does it cost money to use Facebook? Is it true that Facebook is going to charge to use the site?
Facebook is a free site and will never require that you pay to continue using the site. You do, however, have the option of making purchases related to games, apps and gifts. In addition, if you choose to use Facebook from your mobile phone, keep in mind that you'll be responsible for any fees associated with internet usage and/or text messaging as determined by your mobile carrier.
