We talked a lot about that and gave it careful thought. If we were serving a consumer market, we might have done it differently than for B2B. I don't think its blackmail to want to know who you are talking to. If people want to enter into a serious conversation with you, the first thing they are going to do is identify who they are. Being interested in who you are talking to is really a matter of courtesy, not blackmail. We make it easy for people to identify themselves by being able to register their contact information so they only have to do it once. On rare occasions we get a complaint, or we get someone who fills in bogus information. But far more often we get compliments for how easy we've made it for people to get the information they need. I even had a case recently where a freelance writer had tried to call one of our companies and wasn't able to get through to someone who could help her. She went to the website, filled in a "contact us" form, told us she was on deadline and left her email and phone number. We had someone back to her in a matter of minutes.
