I've done a lot of work on TypeTango MBTI Personals - Myers Briggs/Keirsey/Jung Dating - Find your match by personality type. It is now possible to search by distance, the search displays picture thumbnails, and it's possible to give different weights to different keywords. The next major project is to consolidate different words for the same concept into a standard form. For instance, it should not be possible to enter both "atheist" and "atheism" as keywords, but only "atheism." I'm also starting to seriously consider making the statistics publicly available, but without the keywords (because I'm still convinced that showing keywords will encourage conformity). There are 426 registered users, which means I've been getting around 4 new users per day since my last journal entry.
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.
