I almost feel like that's out of scope for your project. The "plus/minus" dynamic plays out organically on places like IRC, Stackoverflow, etc. Whereas finding an equal is somewhat harder.
That might be true. I think it might be bordering out of scope for the "Find Study Buddies" feature, but I've thought about potentially adding a Q&A feature to the site in the future, which might be more in scope with the site in general and also address the "Plus/Minus" component.
