LinkedIn. I was at a conference of recruiters in Denver a few weeks ago and met Traci Enos there. She has been a top 1% professional on LinkedIn and took a completely different view of it to get there than most people do. I scheduled her for Job Search Radio while we were there because I really thought she would tell you many things that would be incredibly helpful.
