oh no. Another "flat design" theme. A button must be distinguishable from other design elements in my opinion. I hope this fad goes away soon, it's even more annoying than the glossy look or skeuomorphs.

Nothing is more annoying than skeumorphs. :)

It should be distinguishable, not just from the theme. A good UX/UI design will make that clear regardless.
