Quote from Governor Gretchen Whitmer's 2026 State of the State address: "Our laws have made it easy to expand suburbs but hard to build walkable downtowns and main streets or do more with your own property. It shouldn't be so hard to build the homes people need in the places where they want to live."

Especially if you're on the fence about it, protest today. Fascism is isolating and lonely. Its very goal is to make you feel like you're the only person unwilling to accept a cult of personality. On days like today you fully realize there are more of us than there are them. You will feel better.

Is the WebDev Arena truly measuring webdev coding ability? This ML coding benchmark *requires* React/Tailwind and completely breaks with vanilla JS/other frameworks. The second-order implications of models competing on this narrow definition of frontend web development are rather troublesome.
Screenshot of https://blog.lmarena.ai/blog/2025/webdev-arena/ showing the system prompt, which includes:

> You are an expert frontend React engineer
>    - Create a React component for whatever the user asked you to create
>    - Use Tailwind classes for styling.
