OK, this may be way off base, but it's amazing what you can think of when you do nothing in school for 6 straight hours. I was thinking about all of the posts I see here about marginal situations in low limits. What I was thinking is that these situations do not matter really. At those limits, there are so many wasted bets by the other players that the difference between value betting and calling a river is so miniscule over the long run.
There is little EV difference in the two plays. These situations are much more important at higher limits where people aren't exactly giving away bets. I think more of the lower limit posts (Even as high as 2/4) should be geared towards correcting glaring mistakes. Most of the longest debates I see in limit are over hands that a different play wouldn't mean much of an EV difference in the long run. The situation is so marginal that playing it differently will result in a better winrate, but it will be very small in comparison to what your winrate could be at low limits.
Not really a huge point here, just an observation I had, and thought I'd throw this out there.
