Reddit launches in 2005 as a link-sharing site and grows into a voting-driven community that decides, collectively, what counts as interesting on a given day. This Off Book episode from PBS talks to co-founder Alexis Ohanian about the site's original design, then brings in Redditor editor Blair Drager, Daily Dot writer Kevin Morris, and Memefactory researcher Stephen Bruckert to explain how upvotes and subreddits turned into a machine for generating memes, AMAs, and viral news. Two moderators of the Shit Reddit Says subreddit appear anonymously to discuss the site's harder edge, including harassment and the arguments over what free speech should permit in a space with almost no editorial gatekeeping. The film also covers Reddit's role in mobilizing opposition to SOPA and CISPA, tracing how a forum built for sharing links ended up shaping congressional debate. Interviews carry most of the film, cut against screen captures of threads and comment sections, and the piece keeps returning to the same unresolved tension: a community that governs itself by upvote, and what that does and does not fix.
