Hey Hacker News,<p>I just built this tool around uncovering Facebook advertising interests.<p>For each keyword you put in, the Facebook™ Ads Manager shows the only 25 interest suggestions, the same that it shows to everybody.<p>Turns out more interests are just an API call away. If you are a dev, it's pretty simple but I thought to put a UI and some more features into it.<p>This was a small feature of a product I built almost three years ago and decided to give it new life.<p>Hope you like it!
