More about me →What I'm focused on right now.
## Building
This site, my first on EmDash, Cloudflare's new Astro-based CMS. It's where I'm testing EmDash before I'd trust it with anyone else's site.
## Writing
A twice-weekly blog on matchlessweb.com about websites, search and AI, drafted with AI, checked by blind AI critics against the pages that already rank, and fact-checked again before anything publishes.
