command line social networking

We all agree myspace, facebook, etc.. are shit. You spend your time looking at stupid stuff and you give a big company all the data it will ever need to create a product exactly for your needs with automatic advertisement buyer. So how can a little geek like me keep in contact with this friends and find out what really matters.
The idea: A command line tool that connects to a server and then you have your personal profile with what you are currently working on you can join the group "C++ developers" or "Linux is BSD without brain" and to be honest what to people like best "flame wars" what a better place to put this and take it away from the mailing lists.
Further everything is done like cvs/git so you can see what your friend has changed etc...
You might have your software backup somewhere or something like that.
I have to think about this a little more. But please comment

What it needs :

• Profile page
• Friends list
• Fotos?
• Groups
• Mail
• Who viewed my profile last
• Current activity
• Link people to content
• Pinboard
• Change log
• Mood indicator [hacking/sleeping/...]
• Encrypt a file amongs many users with secret shareing. So only when all users click on share the file can be read
  
• ??????

One big problem with social networking nowadays is the security issue. So when you add a friend to your buddies list you exchange public keys. So you can sign every message you send. And only with this key can you read his profile :)
