Hi,
I have to make a decision for our (eXma german) community webpage. We will relauching it with a new system.
There are two sites: The first is to develop a whole new system on e.g. Django and Python. The second is to use the new Drupal 7.
Personally I have a lot more experiences with Drupal 6 and now since I'm testing Drupal 7 on my local system, I think it's a very good system with a very good API to build a growing community page with some custom module developments. But the other side thinks it will be better to develop a whole new system based on Django / Python (because PHP is a bad language in their mind... but I think it's never mind) because Drupal does not scale as good as a system with python (but we have only 15000 users at the moment...) and a own system is better to manage because we know the code.
Can you help me to make a good decision? I prefere Drupal 7 with some own modules, we will develop. Because Drupal has a solid core of the central modules we will need for our community.
