Building stuff "just because"
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.
Sometimes the idea will go somewhere, and I'll build an entire project around it, like Chronolists or MakerAPI.
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.
