I dont think its reading comprehension, I think his first post sounded as though this was something new and he was writing a book on it, when in reality it has been in 4 issues of Alpinist including the most recent one, as well as a plethora of other books. He asked for input and I think most people told him that there was a bunch of stuff already and he should try there. In fact, and I think you would agree with me here, all the replies have been quite cordial and un-cc.com.
