A rather disappointing read. I was expecting an analysis explaining why there is this trend towards very sparse interfaces, or practical ways of designing interfaces that are denser in the face of design trends that are pushing all product teams to do ever more spacing out.
Instead, what I found was a reminder of the ‘laws of design’, which are certainly interesting, but which are only tangentially linked to this drift (in my opinion); and to take the most extreme example of sparse interfaces (the Bloomberg Terminal), without really any concrete elements that could help bring a little density back to our user interfaces.
...not to mention what ends the article, a lunar explanation along the lines of ‘Google's very high stock market valuation compared to Yahoo can be explained by the lack of density of its home page interface’ - really? Come on.
