To build a feature rich and scalable social networking site in Drupal today, which Drupal is the best place to start?
The choices I am aware of are D6, D7, drupal commons, Open Atrium, Managing News, and Open Publish. Are there more?
Where do you start to build a site that has most or all of the functionality in the bundled projects and further site specific customization?
This question may be of interest to many looking to build something big and new in Drupal now. I have a subquestion that is more specific to the core structure for my project.
What the best way to support wiki-style topics with a fixed number of related sub-topics, where the subtopics, support their own discussion threads and other basic social networking features.
I have a D6 test working using CCK Nodereference where the subtopics are created and destroyed along with the topic node. There are currently 8 subtopics, like sections. I am wondering if there are better approaches, and also wondering if this will influence which project to begin with.
