It seems like we have come up to a major difference of opinion in the 2.0 implementation of Dojo 2.0. Some folks feel that dd.com should become a "social networking" site, while others feel not. An issue was started in the issue queue (http://drupal.org/node/207006) but I feel this is really a meta discussion that we need to hammer out in the Dojo group so it doesn't derail us.
One phrase that has been tossed out there for dd.com is "a social network for drupal wannabes" but I feel that the Drupal community is the social network for drupal wannabes and making some distinction for the Dojo that requires a totally different infrastructure/website for that aspect is detrimental to the Dojo and the larger community. The best way to succeed with Drupal is to plug directly in to the Drupal community.
I feel that much of what Josh discussed "back in the day" regarding using dd.com for lesson delivery and organization and using g.d.o for the community still is the best plan overall. I also think that focusing on that core functionality for dd.com is key to getting things done. Getting the website up and getting solid video needs taken care of will require a lot of resources as is. We need to start with workable, high priority chunks of functionality. Then once we have that covered we can look at how the site is used, what demands of the Dojo are not being met and then decide if/what a second phase of the site would be.
Basically I'm saying that social networking on dd.com is out of scope for Dojo 2.0. The larger Drupal community is a community and works very well with the existing sites. I think if we want improvements there, then we should work on d.o and g.d.o improvements. At the end of the day a community and "social network" is people not the cool modules you can install. At this point I'm inclined to mark all "social networking" features for the Dojo 2.0 website to either "nice to have" or "no" following the guidelines in http://groups.drupal.org/node/7954.
So those are my thoughts and I'm tossing this open for discussion.
