Short version: not yet, but that’s the plan. We are applying to affiliate programmes. If one accepts us, some links here will start earning us a small commission — at no extra cost to you, and never changing the price you pay. Right now we earn precisely nothing, and this page will be updated the day that changes.
Affiliate links appear in the “How to get even rarer” section, which suggests books and courses related to the traits you picked. They are the only paid links on the site.
Full disclosure about our disclosure: nobody has said yes yet. Here is exactly where we stand.
Until one of them accepts, every link in the improvement section is just a link, earning us nothing at all. Enjoy this rare window of our complete commercial innocence — statistically it won’t last.
Recommendations are matched to the categories of traits you picked — pick language traits, get language courses. We suggest things we consider genuinely relevant to the skill in question. Nobody has ever paid us to feature a product, and if that day comes, a commission still will not buy a placement.
The rarity numbers on this site are playful Fermi estimates, not research. Nothing here is professional, educational, medical or financial advice. Buy a book because you want the skill, not because a cartoon card called you Legendary.
