> You'll get a competent UI with little effort but nothing truly unique or mind-blowing.

Which is exactly what I want. Do you have any idea how hard it is to get a competent UI?

Why do people celebrate consistency and uniformity in desktop apps, wanting to crucify developers for not following platform idioms and guidelines... and then suddenly want things that are "truly unique" or "mind-blowing" or "artisanal weirdness" when it comes to a web app?

A competent UI with little effort is a godsend.
