Redesign of eBay reminds me of an old debate I had with fellow UX designers: is natural language always better than artificial tech language (even if it addresses clear mental model)?
Let me give you an example:
In new eBay UI the text in the search input says "I'm looking for..." - which is a nice example of natural language, but it's followed by nasty "All categories" - which is very close to artificial tech language (would you call shop department a category in offline environment?). In fact though in eCommerce we tend to talk about "categories" all the time, so it might address the right mental model in the head of our users.
If eBay would decide to go all the way with natural language they should come up with something like "I'm looking for... [in all departments]" etc.
To make it even more interesting while eBay uses "category" throughout the interface, Amazon goes with "department".
So the question is as follows: Is natural language always better than artificial tech language (even if it addresses clear mental model)?
