I'm curious, I remember a posting a while back that you were trying to sell this app through Flippa? Any details of that experience you would mind sharing (nothing but tire kickers, not the right market, buyer fall thru, etc...)?
I'm used to selling items on the Envato marketplace, which provides all of the 'advertising' for me. But it seems that with Flippa, there is so much noise and one has to do their own finding of buyers.
