This should be published soon. Thx to all who joined in!

It feels like it's been a lifetime since I wrote content instead of code, but I'm finally back at it! I put together this March newsletter for A11y Pulse, covering what we shipped last month: www.a11ypulse.com/blog/newslet...

New on the Squarespace Engineering Blog! Squarespace & Web Standards: How We Helped Bring HTML Video & Audio Lazy-Loading to Today’s Browsers.

I'm real proud of the teamwork that went into this. Stay tuned for part 2 next week, which will cover dev best practices for using this new HTML standard.

p75 and p90 JavaScript bytes on the web have exploded since May, 2025—easily the largest 10 month period based on HTTP Archive data since 2023.

The long-tail is getting worse, very quickly.

Gemini, what happened in May 2025?

Jim Acosta testified before Congress today warning that a pending merger could hand CNN to Trump-aligned billionaires. He’s never stopped speaking truth to power, even when it cost him. We’re grateful someone is still saying it out loud.

"When people like Kamala Harris send our sons and daughters, our young people, to fight in stupid wars, it is the young generation that carries the burden of that. We're gonna stop sending our young people to far away lands. We are not the policemen of the world."

SpeedCurve | The speed of trust: How slow pages hurt your brand In a competitive market, page speed is as important as your design and content.

A slow UX affects people’s perception of three important brand elements that are completely unrelated to page speed: content, design, and usability.

Here's why that takeaway is relevant in an increasingly competition online landscape 👉 www.speedcurve.com/blog/brand-p...

Shame about the lack of #webperf enhancements accepted into Interop 2026, particularly CLS which would have been really useful.

But there are plenty of performance-adjacent improvements, mainly via CSS enhancements such as anchor positioning and scroll-driven animations: web.dev/blog/interop...

Hi friends. Are you finding that suddenly armed gangs are roving your street deploying chemical weapons like it's candy at a parade? You can go to Menards or a hardware store and get the 3M chemical respirators. They are in the paint section. Smalls exist but they need to be ordered. Stay safe!

AI browsers are straight out of the enshittification playbook • Cory Dransfeldt Enshittification isn't cliché, it's simply pervasive. Browsers being launched by AI companies will, undoubtedly, follow the same playbook we've seen over and over again.

"Websites that work perfectly in traditional browsers may end up broken for actual accessibility tools. The web will fragment as sites must test against a growing number of AI browser agents with different requirements." www.coryd.dev/posts/2025/a...
