In my opinion dolphins matchmaking doesn't make any sense for dating and social sites. Because of this I developed my own one with questionnaires and lots other stuff. But in the end it still uses the underlying score engine.
Big dating sites use completely different approaches based on MBTI / Big5 etc. Even it is proven since 2012 they also do not work they are still better than that what Dolphin provides.
I suggest a complete redesign of the underlying matchmaking code to a more algorithm based solution. So how it should look like?
Some days ago scientists presented a new algorithm that sounds very promising and lots big sites alteady are interested in it. Dolphin should also go this way and Boonex should put every resources in it to be one of the first. News and media coverage will be guaranteed! Just use Google for some articles about it, I only have a draft of the algorithm that can be found here.
