But about the burger example: Would I buy a burger from the shop with the… extreme site? You bet. Would I buy a burger from the shop with the “modern” site? Less likely! If I had to guess why that is, then maybe it’s about the effort that went into designing the page. The first site may have shit UX, but it at least they went all out with the design. The second site may have better UX, but its design is a soulless husk. No quirks or anything, just 100% boring.
I often miss the old times. The frozen food delivery service I use also had a re-design recently. The catalogue now looks like generic magazine movie prop. At least the new website isn’t as terrible.
