Zip Recruiter, until they fail also. I honestly use the ads in my podcasts as a way to know what companies not to invest in. Anyone want a used Quip toothbrush or some Me Undies?
But to JohnJamesRambo's credit, there are a lot of people who don't 'invest' in the US government either.
Of course, I'm not sure I'd want to invest in Brexit, so maybe it still holds.
