I bought the first edition of the Indonesian Playboy. I say it was very dissapointing. I was so hopping to see something, but nothing. I did get a good laugh when the FPI (a militant Islamic group) were demonstrating and I asked one of the members wether or not the girl on the cover was hot. He said, "cantik banget pak." (Very pretty)
I think Indonesia is the 4th most populous country in the world, and the largest Islamic country in the world as well. As to how secular they are I could not tell you conclusively.
