One of the pieces of advice often given to PPL students is to hang around at the flying school or club and to get involved in the conversations there - not just to turn up for their lesson and go home straight after - because they'll learn lots from the discussion. Same goes for folk later in their flying careers - the reason for the barroom discussion is that we know we need to keep on learning and that the views of others and their experiences are a great way to learn.
This place is the internet version of the flying club bar. So yes there's lots to learn here.
But just like any clubroom you have to work out over time who is worth listening to, who is going to exaggerate, who makes it up as they go along, etc etc
