Its really simple to create a scalable social network using Redis, to demonstrate this I wrote a small library called "resn" in python that can provide out of the box support for friends, news feed, asymmetric connections (like Twitter) and authentication. It uses the redis-py library by Andy McCurdy and Amir Salihefendic's redis_wrap.
It can be used along with any python web framework including django, flask, pylons etc .This library can be used by app developers who need to create mini social networks and can be found at https://github.com/vivekn/resn/ Hope this helps, Vivek Narayanan -- http://mail.python.org/mailman/listinfo/python-list
