+    Since the dawn of the world-wide-web, the internet has been a battleground
+between the "big boys" with all their resources, and a bunch of upstarts whose
+goal is to topple the status quo - and bring the same powers of global reach 
+to anybody with a computer and an internet connection. 
+
+    The latest battleground is social networking. Many of your friends would 
+have you believe that the world (and all the information in it) belongs to 
+Facebook. 
+
+    Friendika is here to rock that boat. 
+
+    Granted, all your friends aren't here - yet. The people who made fun of you
+in high school (yet curiously wanted to be friends with you now) are still
+"poking" each other and managing their virtual farms and telling you all about
+their virtual gang wars. Would you miss them? 
+
+    I wouldn't. 
+
+    You probably have a handful of friends that are truly special. Tell those
+friends that the world has changed - because it has. It's time to move on. A 
+year ago, if you had left Facebook, there was no place to go - at least a 
+place which offered the same kind of social interaction (and wasn't just
+another huge company trying to make money off of all of your private
+information).
+
+    Today you have options.  
+
+    What if there was a social network which provided some of the same
+interaction you've grown to love, *and* was free to use, *and* was open source,
+*and* where your privacy is always under your control?
+ 
+    And what if this social network could scale to encompass the entire 
+internet, and *not* require a central organisation to provide servers (in 
+exchange for selling your private information; and everything else they can
+find out about you - from logging all of your online activities and
+conversations)?
+
+    Look no further. 
+
+    Friendika is a social network without boundaries, and without ownership. 
+Friendika installations can link together into a global social network which 
+is free from central control. Besides the Friendika network (which is privacy 
+enhanced); you can also connect with and communicate with friends on identi.ca,
+Status.Net and many other sites and social networks *today*. 
+
+    Welcome to the federated social web. If you choose not to use Friendika 
+(though we think you'd be foolish not to), you can choose any of 20-30 other
+providers of federated social networking software and still be a part of this
+vast new social network. This is going to be bigger than Facebook. 
+
+    Much bigger.  
+
+    We are currently developing connectors to seamlessly communicate with many 
 other open social networks and providers - like Diaspora, GNU-Social,
 OneSocialWeb, and even some of the larger closed services such as Facebook and
 Twitter.
 
-Over the coming months, the boundaries between these networks will start to

+rarely are (straight-forward and simple). Whether you're communicating with
+drinking buddies or potential employers, you can rest assured that each is
+only able to see the side of you that you wish to present. If you send a
+private message to your aunt Mary, we will encrypt it with military grade
+encryption.

 communities. This makes it an excellent choice for the social networking needs
 of young teenagers and especially k-12 organisations.
