how can I rate the quality of information in the articles?
There are some articles that are biased with some real misinformation. One person has an experience and the author is purported to be an expert just because they have some degree with little or no relevance to real world people, just some niche group who would like to be considered mainstream. As much as I love the start page with some interesting articles, it seems most days lately, theories put forth as facts are out of touch with mainstream America.
