Dumbledore "outed" by Rowling

Recently J.K. Rowling let the world know that the much loved Dumbledore is gay.  Although this does make his relationship with Grindelwald make sense, it doesn't really affect the books for me.  Did she have to do it?  Well, no.  She was asked a question and she answered it is as simple as that. 
There are those who say there was an ulterior motive, well, she IS a business person, of course she weighs how things affect her and her  product.  Hey it worked, here we are again all discussing the book and people will be searching them now for hints to Dumbledore's life. 
Rock on Rowling.
