"Comparing Wal-Mart and Target on Facebook", from Emergence Marketing.
"Target has over 7,000 members and mostly positive comments in a vibrant set of discussions. The Wal-Mart group on the other hand has a little over 1,200 members, no discussions are allowed, and the wall postings are mostly negative."
It appears Wal-mart has not learned much from their earlier endeavors on the net. These days customers are king and it is about abundance.
Anyway, we've been working on some Enterprise mashups - Creating Facebook applications (mashups) using a lot of the functionality, user management, authentication, content (images, video, text), groups we use in Drupal web applications.
