I agree with everyone about Rajan Khanna. Actually, I do have another piece in mind for him to read, and it's not Indian-themed. (Our readers do sometimes decline projects, though, of course, so I can't guarantee anything...)
Just to let you know, Ragtime, Escape Artists doesn't have an acquisitions department. The podcasts buy and schedule stories separately. We don't even talk about what stories we're running with each other in advance, so the preponderance of prostitutes in the last couple weeks is just one of those flukes that happens sometimes when you collect a bunch of stuff in a random order. Sometimes, they just happen to coincide.
Jackie Mason once objected to the sex scene in a movie and was told, "But Jackie, sex is very important. Everyone does it", to which he replied, "Everyone drinks soup. Where's the soup scene?"
Four podcasts in 3 weeks about Soup might be a coincidence. Four about prostitutes (Maybe there were more in Escape Pod and Pseudopod -- I only listen to all of the Podcastles religiously) is a sign of something else.
Perhaps you don't read comic book, but among we small group of individuals who think of ourselves (at least in part) as "Feminist Comic Book Fans," we keep a lists of female superheroes whose back story ("Secret Origins!") include either rape (Black Canary, Hawkgirl . . .) or prostitution (Catwoman, Speedy . . .). Actually, we keep a list of female superheroes whose back story does NOT include either rape or prostitution, because that list is much, much shorter. It is basically "only Wonder Woman." No prominent male superheroes, on the other hand, have a back story that includes either rape or prostitution.
So, when we hear a story with only one female character, and that one character either (a) is raped, or (b) is a prostitute, we immediately notice (and then check to see if Frank Miller wrote the story). We would never consider that three stories involving prostitutes in the same month would be "just a coincidence."
