Open Library, the other main thing I've been working on, is set to go 1.0 this week. So I guess that could be a qualified success. I did a more detailed review of projects on my blog: http://www.aaronsw.com/weblog/projects2007

Jobbook was a project I was doing with Seth Roberts; it got abandoned largely because Seth's publisher demanded that he stop working on it and focus on finishing his real book. If someone else wants to pick it that would be cool; I agree it addresses a real need.
