Steve Huffman is co-founder and CEO of Reddit, the website that bills itself as "the front page of the internet". In this extended interview, Huffman tells Amol Rajan about his "pathological dedication" to Reddit's policy on free speech and moderation, why Reddit has always had an "anti-establishment edge", and his own mission "to fulfil the promise of the Internet". Earlier this year, Reddit hit the headlines after a community of amateur stock market traders set out to inflict losses on hedge funds that had bet against GameStop, an unfashionable US retailer.
