I'm about 75% of the way done moving my old wordpress blog to a Django powered site I built, its been a pretty interesting experience.<p>
That said, all these showcases show is that the people who built them are good visual designers, and doesn't really have much to do with Django. Its great that they are good designers, it can be really hard to design a site that looks great (I know I struggle to do so), but how they look doesn't have anything to do with Django.<p>
Dpaste is a cute project, I ended up implementing code highlighting in my blog with Pygments (the library that is used with Dpaste), and its incredibly easy to work with. I'd love to have something similar here... but porting the BeautifulSoup and Pygments libraries over to Arc would be moderately large projects (could we port them over to Dr Scheme and have Arc call that?).
