The site’s gone through a few iterations in the past. It started life as a plain old WordPress site, then became headless WordPress powering an EmberJS SPA using bootstrap, and most recently has morphed into a NextJS / React / Tailwind site pulling from a WordPress API.
I think when you learn a new framework and you’re desperate for ideas for things to build with it, your own website is a pretty easy one to run with. And that was the case for me with React, having tried it on a contract and deciding I loved it. Plus I’d moved more towards using Tailwind from Bootstrap as I became sold on utility based CSS, and Tailwind provided that plus the flexibility of easy customization.
