Recently this website has turned up on a lot of my google searches. They have articles about almost everything under the sun: health, technology, parenting, entertainment, .... Here is how they describe themselves: I am particularly interested in nutrition and healthy lifestyle choices and about.com keeps turning when I try to learn about these things from the internet. For some random recent examples, I found some info on heartburn and ingredients of energy bars there that would be pretty helpful if I can trust it. So, I am trying to gauge how reliable the information they provide is. For instance, I am trying to figure out how it compares to Wikipedia. Is it just like Wikipedia except with restrictions on the article-writers? They claim that the people writing their articles, called "guides", are experts benevolently interested in helping people. That seems possible and it would be really cool if it were true, but I am pretty wary of claims like that. The devils advocate in me says that about.com could just be a lor of business people trying to make money off advertising revenue. I couldn't find whether it was nonprofit or not. Anyway, what do people make of this website? In general, when you look for advice about random encyclopedic knowledge about things such as food, nutrition, historical facts, diseases, government, technology, on the internet how do you judge the credibility of the site?
