I built what I guess is a LinkedIn alternative: https://sifted3.com/blog/building-sifted3

It's less focused on the social, more on the jobs. With a limit on the number of job applications a user can make; sort of like Twitter, for job application count. And mechanisms to provide feedback to users. Basically trying to address a few shortcomings of LinkedIn as I see them (with other mechanisms in the pipeline).

But it has neither any jobs, nor candidates.

I'm not sure what the strategy should be to resolve that. I've tried a few things that haven't worked out yet.
