@FabianHedin @_ChrisCovington @tan_stack Would love to see that happen! Honestly more than a bit surprised to see such a big announcement without a paragraph about sustaining the development on the dependency you just introduced...

Anton Osika is also one of the faces of Balderton's "Built in Europe" campaign, launched the same day as the TanStack migration post.

Funding the commons should be one of the things we Europeans just do.

Lovable just made TanStack Start the foundation of every new app it ships. ~100,000 new apps a day.

TanStack has 13 named public sponsors across Gold, Silver, Bronze. Lovable isn't on the list.

At $400M ARR and $6.6B valuation, that should change.

@LucasRolff Well -

1. Shouldn't you cache your pages better?
2. I didn't say in my blog post you shouldn't rate limit :)

[Joost de Valk @jdevalk]

This week I shipped an MCP so AI agents could read my new specification .website. Also this week, one of my hosts shipped a CAPTCHA on another of my sites. To keep the agents out. Only one of us is reading the room.

[Joost de Valk @jdevalk]

@LucasRolff Yes... And those can be entirely valuable visits. I don't see your point?

[Joost de Valk @jdevalk]

OK but your pull request is a bit minimal in the info it provides :) Let me see if I understand it well.

As far as I understand it, WCAG 2.4.1 requires a mechanism to bypass blocks.

Skip links are one such mechanism, proper landmarks (<main>, <nav>) plus a sane heading structure also satisfy 2.4.1 for screen-reader users. So the spec page is about a specific technique, not the outcome.

Wouldn't the cleaner move be to make a bypass-blocks page? We could set that to required, covering landmarks + headings + skip links as alternatives, and leave skip-links as recommended (as it's the most common implementation of that outcome).

Would love your input, as well as @heyamberhinds and others of course.

Launching https://t.co/36UBUXMmiq.

A platform-agnostic spec of what a good website does: SEO, accessibility, security, agent-readiness, performance, privacy, i18n.

Every claim cites a source. Ships with a checklist, llms.txt, MCP server, and Agent Skill.

Free. Open Source.

@lilyraynyc @AndyBeard @glenngabe The .md exists too but should canonicalize back. (I just noticed i broke that on my blog)

@DerekAshauer @ajaydsouza Sorry for your loss but I’d love to hear how it went

[Joost de Valk @jdevalk]

@ireDave And I disagree - I see it actively being hit on developer sites. So it might not be worth it for everyone, yet. But the minute it becomes more mainstream, if you took the 5 mins to add that file, won't you be happy you did? If it takes months to add it, of course you shouldn't.

[Joost de Valk @jdevalk]

@ireDave nah, that's nonsense. One, the listicle doesn't help you much, and two, creating an llms.txt file is a task an agent can do perfectly fine so for anyone reasonably apt with Claude or ChatGPT it should be a 5 minute job.

[Joost de Valk @jdevalk]

@ireDave you don't have to agree - I wrote about this recently:

https://t.co/ZkJVxaRcBc

Also - looking at the stats for people using the site already, 30-40% of traffic in the last few hours was agents requesting pages as markdown and opening the llms.txt (which, admittedly, is linked)

[Joost de Valk @jdevalk]

@Bovelett PRs are welcome 😅

[Joost de Valk @jdevalk]

I spent over a year on FAIR (the federated WordPress alternative). The lesson: Open Source First in procurement isn't enough without funding the commons it depends on.

Why I'm signing the SUSE letter to the EU, and what's missing from it:

@briancoords If it’s a genuine question, maybe don’t call it FUD before you know the answer.

[Joost de Valk @jdevalk]

@jeroenvonk_ Maybe like 3

Because you all need a cocktail MCP server.
