These sites work on network effect, pretty similar to social networks, I guess. It helps to get a reasonable product quickly out there that does not compromise too much on the user experience and privacy. In India there is a job site called naukri.com that has horrible user experience, but is still the number one job site. But it works and does the bare minimum without much issues. It would be tough for anyone to crack that market without non-trivial capital.
