Here is my take... it's like panning for gold, there are genuine nuggets out there but you need to sift through a lot of worthless dirt to find them. When I have the knowledge to answer a technical question I make it a point to reply with serious, valuable, detailed information. The aviation community really needs a valuable forum for the dissemination of important, factual, unbiased information and POA could be it. The problem, of course, is that many contributors are offering uneducated opinions, sarcastic commentary, and off-topic dialogue.
