I definitely like to know, primarily so I can determine where my advertising money/time is best spent. Occasionally I've been led to boards I didn't know existed, and ads I didn't know existed (many sites will post them without our consent). Also, if I can read his prior reviews or posts, I get a better idea of the kind of experience he's interested in and if he has any major likes/dislikes. This is a
good thing for him.
I agree with the lady you saw -- not everything you read in reviews is the whole truth and nothing but the truth. Sometimes review writers have a different perspective than the lady on how the date went, have faulty memories, embellish the experience to make themselves/the lady look better, or just plain lie for whatever reason. Interpret what you read in reviews with a grain of salt, especially if they're not reviewers you know and trust.
