Craigslist in the summer of 2003 is already a phenomenon: over a third of Bay Area internet users check it regularly, the San Francisco board alone takes in 23,000 posts a day, and the site has spread to 31 cities on word of mouth alone, with no advertising. Filmmaker Michael Ferris Gibson sends eight crews out on a single day, August 4, 2003, to follow whatever postings turn up. A drag performer doing Ethel Merman auditions backup musicians for Led Zeppelin covers. A suburban woman organizes a support group for owners of diabetic cats. A couple searches for a rabbi willing to marry them, a woman looks for a sperm donor, and a man offers computer repair in trade for a used car. Interviews with the people behind the posts alternate with glimpses of the site's bare-bones interface and the sheer range of ads scrolling past it. The film treats none of these stories as more important than the others, building instead a composite portrait of one city's ordinary needs, made visible all at once by a free bulletin board nobody runs like a business.
