The whole idea of Mistresses talking to Mistresses, excluding their customers and flaunting the forum in front of their customers with different colored fonts to show if they are members of the page, reminds me of this exchange:
"Inherit The Wind" (1960) is a movie based on the famous Scopes Monkey Trial in Tennessee during 1925. A teacher is arrested because he broke the local law about not allowing evolution to be taught in schools. (As the events in the U.S over the past few years shows, history does repeat itself.) Defense attorney Henry Drummond (based on the actual attorney Clarence Darrow) has this exchange with the radio announcer in court right before the decision is rendered.
Henry Drummond : Radio! God, this is going to break down a lot of walls.
Radio Announcer : You're not supposed to say "God" on the radio!
Henry Drummond : Why the hell not?
Radio Announcer : You're not supposed to say "Hell", either.
Henry Drummond : This is going to be a barren source of amusement!
That forum will be an echo chamber, with few dissenting voices, and will quickly become a true "barren source of amusement." I'm very happy customers like me, and that's what we are fellow subs, will not have to endure such a forum.
