I doubt, that anybody minds if the spectators gamble/bet on pool matches, aslong, as there is a good control body, that looks after the players...
It would be unacceptable to have players bet on themselves or even tournaments they are in...
Suchthings ARE looked after in snooker (even though they had their own issues with that, if i understand things right ... (however in the snooker world this kind of issue would actually lead to punishments)
I think, that Snooker has of course a bunch of personalities and drama, the dress code and the TV layout with referees that have a professional appearance, a level of difficulty that is obvious for anybody who has seen a snooker table or triedto pocket balls (which makes it much easier to accept Ronny O'Sullivan or Jimmy White as a hero that does something magic, than Ralf or SvB run a 9 pack in 9-Ball with not a single difficult shot, because they position every ball in a way most ball banger in a pool hall could make them ... only few can understand how much skill that needs)
I too agree on the attraction of all of this creates for the female crowd... i never heard my wife talk about pool (and she plays herself!) players, but she and her friends we discussing Neil Robertson playing Ronnie O'Sullivan on facebook ... (surely this had nothing to do with appearance

)
I honestly doubt, that american pool can every attract the masses as well ... We should be able to achieve a certain coverage however ... We just cannot be more boring than curling
But what you need are guys like Efren Reyes, Django Bustamante, yes some Earls and Dennis Hatches and guys like Thorsten Hohmann and Ralf Souquet and advertisments for these players ... Thorsten looks smart and plays beautiful straight forward pool, then oyu got Ralf who does the same but looks a bit more casual doing so ... you need some bad guys that people can hate and love ... Dennis Hatch is a perfect example ... he CAN raise a crowd, if he is on fire ...
you need some people who are just magical heros like Efren (Jimmy White) and some tragic heros like Django taking so many years on the top lists to become a world champion ...
We DO have drama to sell ... But we do noteven buy it ourselves ... why should anybody outside of the scene do???
