You should put together a screencast demonstrating the product. A few paragraphs and a brief, general description of the product didn't convince me to sign up to check it out. People will want more information on what they're signing up for. You should put particular emphasis on how easy it is to review resumes. Also, make sure you point out what differentiates you from Monster or Dice. You don't offer job listings, just application tracking, and people will be unsure of why they should use your service rather than a job board. Great idea though.
