Facebook have been around for more than 5 years making and sharing with friends from all over the world. Yet as the number of uses grew to about 350 million, Facebook CEO Zuckerberg states in his letter (below) that it needs to simplify its network settings in order to better protect users from theft and impose a better and more secure privacy settings.
Here is a quote of Mr. Zuckerberg's open letter regarding the matter:
"Facebook’s current privacy model revolves around “networks” —"... as Facebook has grown, some of these regional networks now have millions of members and we’ve concluded that this is no longer the best way for you to control your privacy. Almost 50 percent of all Facebook users are members of regional networks, so this is an important issue for us. If we can build a better system, then more than 100 million people will have even more control of their information.
The plan we’ve come up with is to remove regional networks completely and create a simpler model for privacy control where you can set content to be available to only your friends, friends of your friends, or everyone.".
