This same concept goes for those horrendously ugly, cookie-cutter, inline sales pages plastered with maroon Comic Sans headlines that have highlighter-yellow backgrounds. I've been there and done that, and the facts prevail. As a good/(as in one that creates aesthetically pleasing things) designer, you actually suck conversion wise.

I haven't done much research behind it, but I believe this has to do with why the flat UI is so pleasing. I can only imagine that it is easy for anyone to notice that it's beautiful regardless of technological/design experience/knowledge.
