If you understand her criticism then please share it with us. And I'm not being sarcastic. I don't intend to go check out whatever stuff she thinks is better to figure out what she likes about them. However, if someone were to document something that they liked about them, and then propose such features here then it would be a different story.
Although I will say that IMO its about time we figured out how to make the "first experience" a little nicer, without custom CSS/user settings the place does look a little crude. Which is something to keep in mind. Most of the people capable of changing the site already have it customized and thus might not even experience whatever it is that bothers you or the OP.
