The MBTI Dating Site - Myers Briggs/Keirsey Personals project is doing well. It's up to 151 users, with a total of 449 referers from Google. However, I sometimes get higher matches with people who merely entered lots of keywords than with those who have more similar values and interests as me. I'm going to add the ability to give different weights to different keywords. I already decided on the interface, and the code for it should be easy.
