What I learned this week… is that it is really fun to pick on Facebook because it doesn’t have the capabilities to support product innovation, product development, and engineering. Of course, it was never intended to and that is probably not a market that they are really very interested in. But it is fun, and also helps to bring home some of the requirements that are important for social computing in PLM. This post started as a reply to Stan’s comment on my “not building an airplane on Facebook post,” and I realized after about 17 pages of comments that maybe I had better turn it into a blog post. Thank you Stan for bringing up a lot of very good questions.
