As a fan of european modernist design history, I see the current trends and fashions in modern interface design trending towards the modernists of the 50s and 60s, towards the old swiss/international style. As a Designer (software developer) with a strong sense of "duty to the public", a modernist at heart, I see this as a good thing; towards that fabled "Common Standard", that goal of least subjective interpretation possible. It finally seems the fashion is to aim at an unattainable goal that provides improvements all round.
I don't understand how self expression has any place in Design, especially interface design.
If that is your point :)
