Django Dzenlog is a set of models and templates, which can be used to create blogs with different kinds media.
Dzenlog relies on new django's feature -- model inheritance, so you can derive you own models from dzenlog's models and add an actual information.
This is very effective way of the code reuse, because dzenlog will take care about all publishing options, and all what you need is to describe details, specific to you particular blog.
For example, for can create a blog with two post types: textual posts and links to internet resources. In that case, all you need is to define two models: TextPost and LinkPost. Each of these models should be derived from django_dzenlog.models.GeneralPost.
