Congratulations! Never been in this situation, but I tend to be the suspicious type :-) I'd be careful, if I were you, and make sure they're not just trying to size you up and get info about your business (maybe they want to start a competitor? maybe they want to see whether it's a viable business how much traffic you're getting, and then decide whether to buy you out). Paranoid? Maybe. Only the paranoid survive... :-)

I tend to be the same way, which is why were will be signing an NDA before either side talks specifics about anything.

A non-disclosure agreement only prevents them from talking with other people about what they learned from you. It doesn't prevent them from using that information themselves if they choose to be a competitor rather than buy you.
