I don't think I have ever learned anything from some such sites. Distilled, prepared wisdom of people with limited scope and understanding. Who is your source? It this source trustworthy? What are his/her biases and prejudices? At least with a good book you get an expanded argument, for or against which you can argue yourself. These feel-good pages, as I call them, are as good as a fart against the wind.
