Actually, he does make some good points. Having the categories in such a light font, and having the individual options in a bolder font is somewhat askew.
It's like writing an outline, but all your sub-items are in big bold fonts, but your top level items are in a small font.
There may very well be reasons for why they did this, but it's a lot more than "It looks fine, that's all there is to it."
EDIT- Actually, the example of the 'Parental Controls' and 'Activity Reporting' items is a very good one. Why would they have the 'Yes' and 'No' so much more prominent that the actual item you are setting? It would be one thing if 'Parental Controls' was in just a regular font in black, but it's in a lighter gray color. Very odd IMO...
