Innovation in the recruiting space is a really hard task. Most recruiters would rather throw money at yet-another-job-board-and-funnel-source than try something unique which requires putting in extra time and effort.
The last "innovation" I've witnessed in the space was the Hired model, and everyone is trying different versions of that now. It's a hurtful model that abuses the inefficiencies and lack-of-transparency in the two sided market. (For anyone wondering what I mean: When you sign up on Hired they ask you what your preferred salary range is, then, as of last time I checked, they show _that exact value_ to the companies looking through prospective candidates. So guess what the first offer you get is? Not what a "fair" market rate is, but exactly what you typed into the sign-up form.)
I do a lot of talking to recruiters as part of helping them use our Stack Overflow Talent product, and honestly it feels like taking crazy pills half the time. Having to answer "why?" to "You need to at very least explain what your company actually does, or maybe the tech stack you use" makes me feel insane.
I loved Starfighter, but thinking back what I liked most about it was the content you and Erin and Patrick wrote about it. Your point about "life is too short" is very very poignant.
I guess the whole point of this comment is for me to say I completely respect that decision, you all did the right thing. Trying to convince people who would rather just throw more money at a wall than try something unique to use your unique product is an awful feeling.
I'm very glad to hear your new project is easier to make money off :)
