Okay, so I've been an avid Drupaller these past few years, and my startup runs on Drupal 7 with user referrals, membership site, activity stream, (facebook styled) statuses, and (twitter like) micro-blog, and Organic Groups among other modules. All of these modules are absent in D8, so D7.

A few months ago, I was introduced to Python, and it simply blew me away. That prompted me to pay attention to Django. Now, all of this D7 stuff above can be found in Django.

That's when I chanced across this discussion on Hacker News:

A post by user 'travjones' starting with 'Scalability' in this referenced thread says Django can only go so far in a production site with good load.

So, given that both Drupal and Django will need to 'migrate' to custom code after some incidents of happy virality, does it make sense for me now to 'defect' from Drupal 7 to Django?

Or, can Drupal 7 work okay for the initial traction phase, and then maybe things look up, the magic wand waves, and everything including code changes [hopefully for the better!]?
