Chad's a super cool guy. I met him at a python conference in Nashville and he was using this big cutter to punch little heart shaped holes in pennies to promote his service gittip (later Gratipay). I had mine for years until it was stolen :/ Glad he's still out there doing good stuff! Chad if you read this you really inspired me that day the way you were so cool with random strangers and genuinely an attentive listener.
