Django Endless Pagination can be used to provide Twitter-style or Digg-style pagination, with optional Ajax support and other features like multiple or lazy pagination.
The initial idea, which has guided the development of this application, is to allow pagination of web contents in very few steps.
Documentation is avaliable online, or in the docs directory of the project.
The source code for this app is hosted at https://github.com/catalpainternational/django-endless-pagination.
