Reddit’s founders didn’t set out to save the web. College roommates Steve Huffman and Alexis Ohanian wanted to create a mobile food-ordering service. But their idea didn’t make sense, at least not at the time. It was 2005; the iPhone didn’t exist yet. So they built something else, no less ambitious: a site that promised to be “the front page of the internet.” Reddit was a place to share all manner of memes, photographs, questions, embarrassing stories, and ideas. Users could upvote posts into internet virality, or sometimes infamy. Eventually, they built their own communities, known as subreddits.
