I'm the one on the left.
Just when I was starting to get bored with Facebook, BAM! we go and create a social network of our own. There are a few differences, though. I have serious doubts that Yahoo will attempt to acquire the RhettandLinKommunity for $1 billion, and we won't take your information and sell it to Gap (we wouldn't even know how to go about that).
Now, write on my wall. It will make me feel special.
