For me Wikipedia had the best content and very high ranking, and its "un-designed" interface is telling strongly that making things "designed" was often unnecessary. Sometime ago an "[edit]" link appeared where hovering a section's title. It was annoying and has been apparently removed.
The first thing I do on a new smartphone install is to remove launcher animations, which are laggy and useless. The same with any PC install, either Linux or Windows: go to the settings and uncheck all animations.
Most animations other than simple sliding on mobile apps are also useless. Any the only moving thing that is useful, the "loading..." spinning weel, is often even absent.
So I think it will be like with rounded-shades-UI vs flat-UI: once doing animations is easy and mainstream, it will not be a marker of craftmanship, and will be dropped except when really useful.
