Replace apiary in examples with real API

[marcin-piela]

APIARY has limitations and it will be better to user real working API, ie. hacker news?

@marcin-piela I can take a crack at this, if you still think this would be a valuable contribution!

Hi @mattrothenberg, I think it's not urgent but important to make examples more life and connected to some public API.

But if you like you can create example with CRUD or integration with forms library like final-form or formik
