India was out of the biz for a while promoting her music. About a month ago she appeared on LA Direct's website, so I guess she's back.
Yes, she's been in and out of the business before.
I like India and I wish her success, but I don't think she's a very strong singer. Fortunately for her, that isn't much of a requirement these days, is it? Not having seen her shows I can't speak to her stage performance, but I doubt Beyonce has anything to worry about.
Regarding the number and quality of black women in porn, I don't think it has changed much. Stefano doesn't seem to have a problem finding them. The number who get shot by the big players is the only thing that varies.
I do agree that the market for Latinas has grown in recent years.
