Clone the repo. Push to dotCloud. Done. You just deployed a MongoDB server and a pristine Django configured to use it :-)
As it stands right now I'll build my own little local Sinatra or Flask or Django app and then slowly integrate it with my own database and then flail about with VPS-hosted Apache or Nginx. I'd really love to be able to start from a nice easy deployment foundation like one of these, but retrofitting it onto an existing VPS-based solution is less fun than it oughta be.
We have been using dotcloud for our django hosting since django 1.2.6 and are very happy with the results. Their support is excellent and their platform is very easy to use. Most importantly the platform is very flexible allowing for deep configurability.
How did this get to the front page?
I doubt there's any conspiracy about the upvoting though: Django, PaaS, and YC companies are all popular topics on HN. Having a professional marketer handling the submission couldn't hurt.
