When building Drupal sites today, you are often faced with two choices: Start out from scratch building a solution on top of the Drupal ecosystem, or go with an already made solution in form of a distribution.
We believe in the middle way: Build on top of a platform that provides the solutions for most problems you are facing, and solve your specific needs on top of that platform. NodeStream is what we would like to call a platform distribution, a distribution that is meant to be extended, solving problems in the news publishing problem space.
