The biggest problem our users had, as it turns out, was that there were often three or more ways to solve the same problem (do I post my meeting annoucenment in forums? as an event? in my blog? post it to the non-Drupal classifieds?)
Now Drupal only runs 70% of the site, so not all the results are Drupal related. if the devel group is interested, I'll see if I can get some corporate permission to share the results (if not the actual video) for those who are interested.
thanks for the offer, Ken. IMO, there isn't much that the drupal development team can do to fix this problem. it is an information architecture problem first, and then Drupal can be used to skillfully implement your plan. expecting drupal to address this is unrealistic IMO. -moshe
