Wow...I used the search term brinked suggested above. The first 16 results on Google (I have it set to show 50 results per page), were all from the same domain. Even the videos/news that was interspersed among the results were from the same domain.
For such a generic search term, those results are unacceptable. I can understand, to a degree, what Google is doing. Sometimes for very specific searches there simply may be no better results - so Google displays the best of the bunch from one domain. But for a generic term like "Mac and Cheese Recipes", the results shown are ridiculous.
