Last contribution to github has been on 2010_01_22, which is more than 2 years now. Tagging still works, but will it continue to? Is it just so well written it doesn't need maintaining for such a long time? Or do i just have the wrong source with https://github.com/brosner/django-tagging?
That's just a clone of http://code.google.com/p/django-tagging/ which works perfectly and is a very well written app. There is also a good alternative called django-taggit https://github.com/alex/django-taggit
