I really have to disagree on that one, as a designer. I see a lot of mistakes:

  - Inconsistent font usage.
  - The page isn't centered properly, it's slightly to the left.
  - Light blue on white text.
  - Improper whitespace usage on the "Faster, Safer, Smarter, Better" section.
  - The social network icons, the monitor, and the trophy are all aliased horribly. Someone used the wrong type of anti-aliasing when resizing them.
  - Pink.

And it's just plain ugly in my opinion :/

Listen, a designer spent 1 month painstakingly criticizing and pulling apart smashing magazine (a very famous designer/developer's blog) website's new design: http://www.awayback.com/smashing-magazine-realigned/

Designers are like that. Give them enough time they will find some mistakes in your work and brag about it. As a designer/developer I think I speak for myself and most design community.

Chances are, some designer out there finds your favorite, best work; repulsive and ugly. I can bet on it.

Tim's criticisms weren't at all small nitpicks. That's Design 101. I'm not a designer and I noticed the same things he did.

While it's true that designers thrive in critique, this simply was not an impressively-designed site.
