You've made some really good points. I guess I read the parent post a bit differently. I was looking through for a summary of how the lifestyle difference between soda drinkers and fruit juice drinkers had been handled. When I saw that post, I thought woowee, here's the thread where the answer will come in. A brief synthesis of the page you mentioned would have really helped me determine the credibility of the article. I can, however, understand the frustration with the statement of "this is more likely [some other reason] than the experts' conclusion." More reasonable is "If you've read the full article, how did experts deal with [this other reason]?" If the answer is complicated and occupies a full page, I don't think it's unreasonable to ask for the cliff notes.
