Good point. I think most people aren't aware that it costs €500 - €1000 to post a single job ad on an important platform.

Of course, the rate will be a lot lower for small companies, but with something like this you'd have perfect targeting. And you don't even need any invasive privacy tracking for targeting: Just let people buy ads on specific repos.

Also, at least in my personal experience, people really don't mind job ads. Job ads are the only ads I regularly click on, because I'm curious what companies are looking for (even though I'm not looking for a job)
