More like Person A goes on the site and answers questions, and then Person B goes on the site and does the same. Their answers get put in a database and whenever two people's answers are the same, they're both notified. Something like that. I'll check out Codecademy and start one of their Ruby or Python courses. Thanks!
I guess this could also be an app instead of a site. Do you still recommend going the Ruby/Python route if I wanted to create an app?
