I have been concentrated my last 5 years working on various high profile websites in New Zealand using Django, since version 1.3.
For the past year in 2 companies, I have been mainly converting legacy systems to Django platform. Currently at GrabOne we are typically converting to SOA & PAAS.
some of the sites I've worked on:
I also have used Django to create facebook competition apps, one that gathered over 20K additional page likes on top of 50K and 40K entries.
I am a believer of DRY, and writing reusable apps whenever I can.
