Like I said a few posts back, we are at our worst when we try to create our own learning system thingy.
However, OpenAcademic is not about an enterprise vendor riding the latest trend. This is the marriage of Elgg, Drupal, Moodle, and Mediawiki. Wow! Its like the snickers bar of learning: Lots of the most yummy open source platforms rolled into one.
This helps answer many of the questions I receive like, "how do we decide which to use, wikis, blogs, or social networks", or "how can we make them work together".
The bad part is now I need to update my presentation slides to add this. I'm changing these slides at least once a day. This will make for a significant update. Oh well, who needs sleep anyway.
