Major news sources will always get more overall exposure simply through quantity because they publish so many articles every single day. However, low traffic sites and blogs will get their content promoted at or near the top of the search results when it is indexed in the same manner that the high traffic sites do.
I understand there are sites you dislike which is why I added an Upgrade global filter feature where you can block sites, topics, keywords, etc. that you do not want to see. Other Upgraded users can do the same when they do not want to see content they dislike as well.
