Ask HN: Hosting Django: Heroku, Gondor, or myself?

Hi,

I'm a web-developer, I love working with a django stack (django/postgres/south/redis/celery/etc), and I've deployed apps myself on ec2 or hosted on dotcloud.

I'd like to be able to iterate through some product ideas so I'm very price-conscious. Ideally I don't want to be charged 10x for hosting 10 web-apps, I want to be charged by traffic. For example if 1 app gets sticky and 9 suck, I shouldn't be charged much more than if I had 1 good app and 1 bad one.

Hosting on EC2 or Linode seems great for this, but I'm actually not super-comfortable with the sysadmin side of things, so I'd prefer to use a Heroku/Gondor or something similar.

Does anyone have any suggestions?

Thanks!
