Twist your brain, with the Thatcher Effect: the faces are wrong, but they seem right upside down, because our brain loves to make sense of things, even when they don't.

The absolute STEAMING irony of my phone alerting me to a story that LinkedIn says it’s lost traffic to AI overviews, clicking to see a summary of the story in an AI overview sourced from LinkedIn 😂😂😂

Got a new spam idea ⚖️
#showerthought LLMs rarely reply with "I don't know" to a prompt because we, humans, rarely ever admit online that we don't know something.

Stop turning your website into markdown.
Meaning lives in structure, hierarchy and context. Flatten it and you don’t make it machine-friendly, you make it meaningless.
Yes, AI might fetch your .md file. That’s convenience, not trust, and it won't scale.

A page is more than just a container for words
The latest SEO fad is the idea that websites need a machine-only version. Strip out the layout, remove the “noise”, and hand LLMs a simplified view of your content.

I am proving here that it doesn't care about schema, though. You can write anything in the html as you like and it will be picked up.

Today I proved it is VITAL to include structured data on your web pages for LLMs, such as waddleStyle and reedNumber 😮💨

Apparently, quite a few people didn't know that @withcandour.co.uk build websites as well as do SEO.
We can do that when you want developers but _don't_ want to worry "I wonder if they will f*** this new site up and make my life hell" 😅
