I think this is a major selling point. If developers could upload their CVs, exercise could package together the users yoe + industry experience with the users learning veracity + main language. I think that would be a solid product that hiring people would pay money for.

Shouldn't that make it even easier to monetize? I appreciate the resolve to keep things free for those who can't afford to pay, but a lot of your users are presumably actively employed making 6 figures.

You could follow the Sublime Text model and basically have an honor system—if you're actively employed making more than $X, please pay us. If you're not, you're welcome to use it for free!

The Tech Resume Inside Out [0] uses this model (though not on the honor system) for similar reasons.

Yes. Good idea.

Another thing. There are several podcasts who have a free feed and paid one. Sam Harris’ Making Sense comes to mind with their free feed and a paid one for full access to all content. But they understand not everyone can pay. If one is unable to pay, they can simply email to ask for a free annual membership.

Pay what you want albums on Bandcamp are another example of a sliding scale. Suggested price $10, but artists can define their minimum.
