Very cool. I knew it was too obvious an idea to be missed! Did you read my comments below about how you can maybe "scale up" a vector based on number of years of experience. I think that will work. It makes somebody with 10 yrs Java Experience closer to the target than someone with only 5yrs, if the target is 10 years! -- but the problem is someone with 20yrs looks even worse when they should look better! My problem in my life. hahaha. Too much experience.

I think the best "matching" factor is to minimize total distance where each distance is the time-multiplied vector for a specific skill.
