Simple Social NetworkingCrosswalk is an engine for web-based social networking applications.

At it's core, Crosswalk is very simple. It contains the least amount of features needed to be a fully functioning social networking application. These features include the ability to support Users, Friendships, Accounts, Tags, Comments, and, most importantly, extensions.

The sky's the limitWant to add photo or video sharing? How about allowing each user to have their own blog?

Adding new functionality to the default installation of CrossWalk comes from the use of extensions. The extension library currently houses all official extensions. However, anyone is welcome to develop their own extensions.

Future DevelopmentCrosswalk is currently being developed in php(!) on top of the CodeIgniter framework. Once version 1.0 is released, a python, ruby, and java implementation will soon follow.
