I'm admittedly bias towards this particular board. Ken is one of the pioneers of Medical and Health Care niche pay-to-post job boarding and has grown his family operation into one of the largest healthcare niche job boards on the web.
His site also boasts a large resume database with category specific search capability as well as a broadcast e-mail feature not common on many other boards.
I'll be inviting Ken to this "discussion" where he can post additional comments in his own words. I'm sure he'll do Absolutely Healthcare more justice than I have here.
Thanks Jim. As you know, Absolutely Health Care is the largest niche job board for health care / medical jobs. We've been named as one of the top 30 job boards in both 2008 and 2007 (out of 80,000+ boards), and named as the niche job board for health care / medical jobs that provides the most average response per job posting. We are 10 years old, and will be finishing up a face lift of our site in early 2009. Visit us at http://www.healthjobsusa.com
