Simply put, it's a dog-eat-dog kind of business. You'll be competing with established giants like monster/linkedin/stackoverflow, niche sites, country-specific-sites, other web spammers, etc... This bussiness has built-in churn: if you do it well, you'll loose users. Word might spread, but you'll eventually loose users. So, if you're brave enough to do this, do it differently: - Build something that makes you a better $LANGUAGE developer. - Build something that helps you transition from $JOBTITLE to $NEXTJOB. And put a very restricted job board on it for people that's interested in getting better at his/her job. That brings more value and probably you can monetize it better.
