I agree with that to a lesser extent than you do. But agree somewhat. I'm not irrational.
But we had a firm policy at the old ESPN board where many of us came from that if you didn't post the thoughts before the race and tried to chirp afterwards, you were scorned and ridiculed and lambasted by the entire board. It kept redboarding to a minimum.
People who don't have DRF's or PP's who haven't seen a race thats being discussed(if its over already) have no business telling those who watched a race what they saw.
People who don't post thoughts before a race have no business crowing about how easy and obvious something is afterwards.
Maybe its a NY thing. You do that here at the track afterwards and are liable to get strangled. Its a beautiful thing.
