Dang I love Texas Hold'em.
Yeah a Casino website would be cool with trustable information of each casino and their games. Just be careful not to put bad information of casinos because you can get in trouble with the owners (that's what I think).
Also would be cool if you try and investigate what's the biggest amount of money a person has got, how many times people win good amount of money, etc. So people when they check your website they say "Hey, in Le Flavel Casino more people has won than in DS Casino, perhaps I should try on Le Flavel because my chances to win might be higher.
