Here is a great example that drove my aspiring app developer friend right up the wall: The Hodor Keyboard. Pointless, mindless, maybe took a few hours to make.....99 cents to buy, and several thousand people did. Dev probably made like $2500/hr for the work it took. AND it got coverage in major mass media and tech.

It's success stories like that, for pointless things, that discourage some and inspire others, such as bros lol
