I would say that the bulk of my knowledge about pizza making comes from doing rather than reading. I read a lot on the subject, of course, but I don't always accept as true what I read. I will spend endless hours making doughs just to test out concepts and principles--not for the purpose of just making pizzas, even though I enjoy them as well. I also learned from November how many things held out to be true are not really true after all or have been overgeneralized or stated in a way as to not be entirely credible or reliable. So, that has made me more skeptical and, as a result, I am now more likely to question conventional wisdom, think things through more completely, research areas where my knowledge is weak, and test things out for myself. As a result, most of what I write on this forum comes from personal experience. When I first started, I relied more on the teachings of others, some of which teachings I no longer follow. For areas where I have not tested things out for myself, I cite and give attribution to others for their views and contributions.
