One of the best things about web development, and software development in general, is that I can build anything I want. Whatever idea comes into my head, I can type some symbols into a text editor, and out comes a new thing. Here's a Spotify song with a built in preview button.
Other times it will go nowhere, and it just remains a thing sat on a server. And that's okay. This is why my site has a Destiny 2 reset timer, my Diablo 3 characters, and my latest public pinboard links. Because there was an API there and the thought struck me that I could build something with it.
It's also why I have a button that does nothing except turn the because why not.
