If it helps any, as someone who's been building Django sites for years, I will say that while all of those are at least handy, absolutely none of them is needed.
On the list, the only one I use with any regularity is South, which I do consider must-have. That said, it seems that the Django core team agrees, as it's being (or maybe is even finished) pulled into Django core.
After that, I personally add allauth, storages, and s3-folder-storages as well, but that's a personal preference thing and there are very good reasons to use alternatives to each of those components.
Totally agree. The title of the submitted most is a bit extreme, these aren't "Django plugins you shouldn't start without" these are "Django plugins that are nice to have". It's false, as the grand parent comment thinks, to presume that django "needs 5 extensions out of the box to be sane".
I've been working with django full time for 3 years and the only one I use is South.
