    Game to remember names, Silicon Valley edition▲6

    I'm terrible at remembering faces and names, especially while networking, so I built this game to help memorize them! To make it more fun, lists and high scores are public. You can create your own lists for an upcoming event you want to be ready for, etc. A group from college had a game like this and it actually got all 100+ members to know each others' names!
