It´s okay for a single person to openly show your dislike for a specific system, there´s nothing wrong with that. We´re only humans.
But completely ignoring a system in the nominations is a different thing, especially for a review site. I´m not talking about the Wii, I´m talking about the DS.
This site treats the Wii as it could be nominated in its own category only (preventing its games from even being nominated outside the plaform category, a category which furthermore only seems to allow 1st party nominations), and it treats the DS as non-existant.
The lack of World of Goo in the nominations is interesting, too...
