Use the mezzanine.blog.models.BlogCategory model for your different blog lists. If you are not happy with 'category/' being in the path, you can copy and modify (below) the mezzanine.blog.urls to your project urls.py.

url("^%s(?P<category>.*)%s$" % _slashes, "mezzanine.blog.views.blog_post_list", name="blog_post_list_category")

To create category templates, take a look at the blog_post_list view and you will see:

templates.append(u"blog/blog_post_list_%s.html" % unicode(category.slug))

To add a template for category "Foo", copymezzanine/blog/templates/blog_post_list.htmlto your projecttemplates/blog/blog_post_list_foo.html. The new template will render if you navigate to /blog/foo/.
