Put another way, the ads give brands like Ally and the non-profit professional organization Project Management Institute another lever to pull on how they show up in generative search. LLMs can pick up a brand’s information from the ad and index it, which can then shape AI-generated responses, which in turn, can...

Remember when I mentioned I was using my Kindle as a personal newspaper? And that this solution was ideal because I didn’t need to buy another gadget? I still stand by that, but I bought another gadget to be my “personal newspaper”: a Boox Go 10.3 (Gen II) Lumi tablet. (Phew! From here on, I’ll just call it the Boox...

I collect cool, interesting links spread all over the web and share them here every Thursday. Hope you enjoy! More of them in the archive. WikiCity. One more creative way to browse (or fly over) Wikipedia. Every entry is a building in a city made up of the encyclopedia’s 100,000 most-visited entries. For the...
Pictures by Hyperallergic. According to the website Hyperallergic, the London-based activist group Everyone Hates Elon pulled off this intervention on a bus-stop ad for Meta’s new pervert smart glasses created in partnership with celebrity Kylie Jenner.
