How does Craigslist make money?
Although they are a for-profit company, they seem content with making a small profit, rather than trying to maximize it like ebay did after they went public. They charge for job ads in about 9 cities and apartment listing in NYC. With Ebay owning about 28% of Craigslist since 2004, it is understandable that the relationship is not the best as Ebay has sued Craiglist and now craiglist has sued Ebay. This is understandable especially since Ebay started Kijiji, which works similar to Craiglist, except they charge for most services.
