Take Github as example. Some people get mad about stars and following and say "remove the social networking cruft".
But even if you do, unless you develop software completely alone without taking input from others, Github is a social networking platform. Someone files an issue in your tracker --> social networking exchange. PR? Ditto.
Just one example. Social networking is EVERYWHERE.
So agree very much with your meme. Huge potential, we can do much more than we *currently* imagine.
