You would to need to give people an idea as to your personality, not just your interests.
Interests don't make a person, their personality does, and it's more often than not that your personality attracts people to you, or repels them from you, depending on their own personality.
I consider myself to have a rather friendly personality, though I can be very annoying, and sometimes arugmentative, both of which are negative traits and would repel people away.
