This is the number of registered people who have tried Smart PropertyGrid beta. I am quite impressed by this figure and for sure I was not hoping so much interest, even if I think that if companies want to display a PropertyGrid in their application it should definitely be something more user friendly than the Microsoft grid that has been designed for developers.
Now this is very difficult to say what sales will be. Do people come by curiosity or do they actually intend to purchase such a product ? At least I have exclusively very good feedback and I am quite confident for the future because Google Analytics gives me a comfortable and increasing rate of revisits.
