Should PLM apps be jealous about Facebook?

I usually think I have nothing to add to discussions about comparison between PLM and social networking. Two facts have contradicted this opinion recently:

  • I had chance to test the Facebook app for iPhone
  • I read the article about Facebook connections as a map

I see here 2 facts:

  • Facebook propose a high level of ergonomics in his iPhone app, far away from ergonomics proposed in our favorite PLM applications
  • Facebook fosters a level of collaboration that any PLM application owner should be jealous about

Is there a link between those facts?
