I don't accept the notion that the "visibility" of accident discussions is reduced because it is here, rather than on Private flying. If pilots are of a mind to review and discuss accidents, they can come here to do it. Once they come to this forum presuming they are inquisitive, they will find other very worthy safety minded discussions too, which they might not have encountered in PF. If pilots can't find this forum from PF, while they are considering a discussion about accidents, well, honestly, they're not trying very hard!
Your growth as a safe pilot requires some effort, nothing good comes for free. If the effort here is a couple of clicks to come to this forum, after browsing the PF forum, is that too much? You switch your mindset from banter about GA, to some serious safety minded thinking for a few minutes - it works for me....
