I think this is a really interesting point. In fact, in a lot of the situations where posters on this forum advocate a bet/fold line on the river, I find that I often use a bet/crying call line, just to guard against a bluff or an overplayed hand. I'm sure I make some bad river calls, but I think there is something to be said for erring on the side of calling too many river raises to guard against forfeiting an entire pot by folding a winning hand.
