I'm trying to determine the best Learning Network to move to from Ning and would love to hear from those who made the move why they picked Grou.ps/Grouply (and the like i.e. Spruz, WackWall, Webs, Big
Tent, SocialGo, Mixxt
) vs a solution like BuddyPress (and the like i.e. Elgg, Drupal, Moodle,
Joomla, LovdByLess, Pligg).
Why did (are you planning to go) the pre-packaged route vs open-source or vice versa?
