Its fun and good site to use for sharing and meeting new people however like all social networks there is always security and age related issues, something you do at your own risk but overall its all good.
Good for social networking, although it's not only site geared to social networking. If you set the privacy settings appropriately and you use facebook wisely you shouldn't run into security issues. Parents be advised that some groups on facebook are probably not appropriate for your children. It can be time consuming as well, but overall it is a good site!
Facebooks user policy means that if you join your details and any photo video or content you load onto the site belongs to facebook, even if you attempt to remove this content they keep a backup of all content in a users profile and retain the legal right to sell this information for marketing purposes. This information may not be removed even if the user requests it of the facebook admin team. READ YOUR USER AGREEMENT CAREFULLY!
Very bad direction with their ads. Did some research on some and some are to dating sites that children should not see and pyramid scams are a high number of them.
Useless, dangerous, once in web, forever in web!
Better think twice before register, social Web is "Highly Dangerous", used ie. by stalker, Firms (Human Resources) and so on.
