I'm still more interested in the purpose behind the intelligence gathering, if that is the reason. It hasn't happened to me (yet), but I suspect that the reason is to either purchase what you've done, or replicate it if it's easy enough to do so or you're not willing to sell. Either way, I definitely wouldn't discuss metrics with someone competitive. I believe this happened to Justin Kan when he visited Google with Kiko. They just wanted to know his numbers, and then they ended up building the product.
