Craigslist is a centralized network of online communities, featuring free online classified advertisements – with sections devoted to jobs, housing, personals, for sale, services, community, gigs, résumés, and discussion forums.
As of 2009, Craigslist operates with a staff of 28 people. Its sole source of revenue is paid job ads in select cities – $75 per ad for the San Francisco Bay Area; $25 per ad for New York, Los Angeles, San Diego, Boston, Seattle, Washington D.C., Chicago, and Portland, Oregon – and paid broker apartment listings in New York City ($10 per ad).
