Discussion: Design: Hobbies and interests questionnaire

[OrAbramovich]

"Roommates" allows its users to select their hobbies/interests. The selection is like "yes/no" question and the matching algorithm that calculates the match score of two people is based on the number of in common attributes.
However, I am not sure that this model reflects real life since there might be blockers e.g. vegan and carnivore.
In my opinion, we should change the "yes-no" questions to "I am - don't care - no way (blocker)".
And the matching algorithm will be modified as well according to the following matrix-

Person A/Person B	I am	Don't care	No way
I am	+1 to the matching sum	+0 to the matching sum	Matching result is set to 0
Don't care	+0 to the matching sum	+0 to the matching sum	+0 to the matching sum
No way	Matching result is set to 0	+0 to the matching sum	+1 to the matching sum

I agree, I actually relied on blockers already when designing the suggest roommates group.

Hi,
Not sure about the score, but I think it's a good idea. In any case, it should be that the scoring-function is configurable (injected to the matching-function).
