If the answer here is to be believed, Pinterest has consciously moved away from Django.

Yes, but that doesn't matter much, since they got to billion valuations just fine WITH Django.

Only one of the main Open Stack projects uses Django - and it is a complete pain to work on as a result.

Most of the projects in OpenStack use Flask or Pecan - or Falcon for one or two of the more performance sensitive APIs

Having used Django and that project (Horizon) extensively, I think that Horizon is not a pain to work on as a result of Django, it was just badly written.
