Personally I tend to stop reading wp-svbtle websites (and I've seen others say the same thing). Whilst many, like yourself, use it because it's nicely designed, to me it feels almost like the blogger is trying to deceive the reader. I like the look of Simvla because whilst the UI is still very similar and minimal, it looks different enough.
Is it really deceptive when only a handful of people (HN readers) even know what Subtle (did I spell that wrong?) is, and they can tell the difference immediately, despite the identical layout?
