Definately!
D&D is slowly moving away from its stereotypical roots and towards a more flexible world, and the Goliath is a step in the right direction. It's very much not a standard fantasy race, and yet it just fits. It also makes for a very interesting character with a very unusual psychology.
And no, that quote does not rub me the wrong way at all. It strikes me as a very interesting racial worldview. If you read further it is explained that it's not just one-upmanship or munchkin bragging, it's the way they measure their own self-worth, and since any goliath PC is likely to be an exile, they've got a lot of making up to do in their own minds.
