Expecting AI agents to adhere to skill files feels like expecting a Strongly Worded Letter to make a difference with politicians.

🚂 Off to London for the “AI and the Future of Sustainability Reporting” event, featuring Jo Lindsay Walton keynoting and lots of interesting panelists.

Downside of attending a conference outside the well-regulated continent of Europe is that no laws protect you from unsolicited spam emails afterwards. 🙃 #GDPRFTW

Wanneer weet je dat de periode die je beschrijft de geschiedenis zal veranderen en wanneer weet je zeker dat iets een voetnoot zal blijken te zijn? Na 7,5 jaar stop ik als politiek verslaggever. Lees hier mijn afscheidsstuk: www.nrc.nl/nieuws/2026/...

our first AB position paper is out: www.w3.org/TR/llms-stan... we tried to very briefly discuss LLMs in the standards process: where they could work and where they could be a problem, including guardrails to do it “responsibly”.

what's the setting in YouTube to get the AI generated captions to contain the swear words that are in the audio? just getting [___] currently, needs more humans in the loop tbh

If you're curious how much of WCAG can be automatically tested (a FAQ I get), this page displays testing rules (ACT) by Success Criterion www.w3.org/WAI/standard... As a companion, there is also @stevefaulkner.bsky.social's excellent “Mind the automation gap” html5accessibility.com/stuff/2025/0...

Tired: keep humans in the loop Wired: keep bots out of the loop (your loop will be more thoughtful and intentional)

Was lovely to present about WCAG-EM 2 today at #CSUNATC, great questions and feedback! My slides are on hidde.github.io/b6-logius/20...

Really good talk by @hidde.blog about sustainability in tech, and a few things we can do to improve the current state of energy consumption. youtu.be/u76IcrzZPwc #sustainability #tech

🛫 off to California for CSUN Assistive Technology Conference, to present and get feedback about WCAG-EM 2, and meet all the peers.

We're working on making WCAG-EM 2 a Note (www.w3.org/TR/wcag-em-2/). A 3 week review period just started, we'd love to hear it if you DO accessibility assessments or RECEIVE reports. Does the “website” to “digital products” change work? Anything else you feel strongly about re reporting/reports?

At CSUN I'll present WCAG-EM 2, a methodology to report on accessibility. We're using WCAG-EM at scale in The Netherlands, with 100s of organisations producing 1000s of reports, somewhat reproducibly. Attend to see how it differs from VPAT+how better evaluations help teams fix barriers faster.

🎥 Out now: video of my @cssday.nl talk on making the web greener at work with the Web Sustainability Guidelines youtu.be/u76IcrzZPwc

The latest Working Draft of WCAG 3 is out today! w3.org/TR/wcag3/ In this version, we've: - moved lots of requirements to “Developing” phase, - wrote down how to test, - mapped reqs to user needs (using DAF), - split out 'applies when' and 'except when' to massively increase readability 1/2

yesterday's State of the Browser may have been my favourite so far! Incredible talks and people, good vibes! Brb just buying next year's ticket

When robots are part of a process, their involvement MUST be identified. Identify LLM output (‘from AI: ’), disclose generated images, and attribute LLM authored code to that LLM. Here's Mozilla hiding Claude's attribution github.com/mozilla-fire... (via @pikesley.mastodon.me.uk.ap.brid.gy)

🚆off to London to find out what state the browsers are in. 2026.stateofthebrowser.com

if you can afford it, often $25 or less a year, get a custom domain name so you have somewhere to always point to so people can find you when they want/need to. having jennschiffer.com for so long has been paramount to my mobility online over the past 25 years

In my slide decks, I've started including quotes of what AI leaders believe to be true, and helps break through the notion that they are some sort of genius magicians. This context matters, if you are to decide about using and trusting (!) the products they make.

Just did a guest lecture on AI and web standards for policy makers. Thanks @lolaodelola.bsky.social for the invite! slides and links: talks.hiddedevries.nl/JrJus9/ai-we...

Heheh, someone wants to optimise AI visibility in my blog post on stealint content by AI vendors hidde.blog/llm-theft-op...

Happy Monday! Today is a good day to tell organisations that are still on / promoting X that its virtual undressing services don't align with the organisations' values. Bonus points if you are a paying customer!

"We published WCAG-EM 2 as a draft note to seek wide input on the current shape of the document. If you evaluate websites or other digital products for accessibility, we'd love to hear what you think."

✏️ WCAG-EM 2.0 lets you report on accessibility of more than just websites hidde.blog/wcag-em-apps

🚅 off to London for our W3C Advisory Board meeting

✏️ I'm back to building my own digital music collection a new blog post, and I'm curious how others do this! hidde.blog/owning-music/

At #SotB22 @hidde.blog talked about implementing best accessibility practices early on in your work. 2022.stateofthebrowser.com/speaker/hidd... We have amazing speakers and topics lined up for #SotB26 too. Join us on 28 February 2026 at the Barbican Centre! 2026.stateofthebrowser.com/speakers/

If you work somewhere that still communicates via X, this week is a good one to petition comms folks to stop using it (generates thousands of sexually abusive images per hour while its owner laughs, FT calls it a “deepfake porn site” www.ft.com/content/ad94...).

Booked my travel for FOSDEM! Looking forward to meeting people and hanging out in the Open Source & EU Policy and the Browser / Web Platform rooms.

Had to teach my 8yo about AI safety and opt-outs today, as their teacher let the class do “research” using a modern search engine.

If I were to turn my thoughts on responsible, irresponsible AI into a public talk that is both critical and reasonable, which conferences should I pitch to? (European preferred)

There may be great use cases for Large Language Models, but note that some use them to sexually assault women online.

✏️ 5 accessibility checks to run on every component zeroheight.com/blog/5-acces... I guest-posted on zeroheight's blog about accessibility of components! (note: WCAG compliance is claimed on full pages/processes only)

Famous for product names like “Teams (for work or school)” and “Windows XP Professional Edition”, Microsoft has just renamed its Office work productivity software. the new name is, and I am not kidding: “the Microsoft 365 Copilot app” www.office.com

Had a new AI tool pitched to us at work that “reduces legacy transformation timelines by 30-60% percent”. dear lazyweb, in what unit are legacy transformation timelines measured? Wrong answers only.

🔗 “The most distinctive element of [ITC Garamond] is its enormous lower-case x-height. In theory this improves its legibilty, but only in the same way that dog poop’s creamy consistency in theory should make it more edible.” (From: I Hate ITC Garamond designobserver.com/i-hate-itc-g...) (via Eric)

Started my 2026 reading log on log.hidde.blog/books/#2026 Inspired by @robin.berjon.com I will keep a thread this year to help you find new reads and make it easy to mute.

I love reading all your annual summary blog posts. Send them my way. pawelgrzybek.com/a-look-back-... So far I have @dbushell.com @bell.bz Cory Dransfeldt @hidde.blog @css-tricks.bsky.social @chriskirknielsen.com Damian Walsh and @loige.co on my list. Send some more my way please! #blogging

✏️ Dear Mozilla, I don't want an “Al kill switch”, I want a more responsible approach for all a new blog post! (*I do want the kill switch, but responsible rollout matters even more in the grand scheme of things) hidde.blog/mozilla-ai-k...

AI generated music made it to Tidal, I saw multiple fake Hiromi albums this week. When I tried to find out how to report, to help them do what's their job, a light gray text appeared. It asked me to rephrase to “help the AI come up with a quick (sic) answer”. ready to go live off grid in the woods

✏️ 2025 in review hidde.blog/2025-review/

Delighted to contribute to the HTMLHell advent calendar. I explained how screen readers don’t always announce what’s visually on screen - through the medium of burritos: www.htmhell.dev/adventcalend... Thanks to experts @matuzo.at and @hidde.blog for making sure the burrito was structurally sound.

AI note taking seems useful, as now nobody needs to take notes. But your notes will be super long and include way too much. Finding the subtle mistakes, misattributions, and remembering what's missing will take more time than writing them yourself (I pledge to do my bit and regularly volunteer).
