Sure, a 'real' book would care- They will be stuck taking on the 'real' wiseguys that really do not care about the screen.
You have your super sharp guys, and, of course, you will have your super suckers- but you don't have any of the pseudo-wiseguy screen hawks(a.k.a clone gamblers) to take any buyback. Unfortunately, these players don't call to get rundowns, becasue they dont know what they are looking for.
Why are books on screen? It is one simple reason, to put the product on the market. Why would they PAY to be on there is they did not need it?
