I've formed a group for Kallah Magazine, featuring this blog, on LinkedIn. You can join the group through the LinkedIn site or at http://www.linkedin.com/groups?gid=1994394. It is interesting to check on people you know there. That is not just a matter of idle curiosity. For example, I had someone listed as a reference who transferred positions. I found him now on LinkedIn, so I now can get updated contact information rather than saying "I don't know. He must have left."
