Facebook your way to a new job?

Dear Annie: I enjoyed your Sept. 30 column, and readers’ comments, about how to decide whom to „friend” on Facebook. I recently joined LinkedIn, which I have heard is a terrific job-search tool, but I could really use some pointers on how to make the most of it. (I lost my old job about six weeks ago and, while my severance pay will last another couple of months, I need to step up my job hunt.)
