I'm not the parent, but: text is spaced out awkwardly, tan text on a tan background is hard to see, orange popping out at you everywhere is distracting, orange twitter and Google+ buttons at the bottom are unfamiliar, the inline pictures look as though the right hand side is cut off.

Even if you don't think these are valid criticisms, the point is that this is all subjective. These are opinions and the OP saying "this is bad and that is good" as though it's law only shows that he misunderstands the audience of programmers who use these sites. I don't program in C or C++ because I thought they have a good website; they have no official website at all.
