In order to find out what visitors to our page actually want, we're tracking where they click.
The item you've clicked on doesn't actually exist yet. We believe in doing things efficiently, and try to test and validate our assumptions before we actually build new features. Your click on this button will be added to the total numbers of site visitors that are interested in this feature, which we monitor on a dashboard. Those features that are not being used get axed, and those that don't exist yet get built. This way, we make sure that our site remains relevant as we, and our products, evolve.
