I want to respond to this.
On something that we haven't heard a lot about or haven't heard come up, especially in the referral conversation, because I'm sensitive to that, my view is that there are other tools available to respond to referrals. When you get a referral, there's a customer out there who's giving you a referral. Nobody has said, “Well, can you ask your friend to e-mail me or send that to my website?” Nobody has talked about their website. You can have a sign-up form on your website. There are lots of mechanisms available to get consent. You can pick up the phone and call.
Somebody talked about going back to the world of Rotary meetings and what not; we don't have to go that far. But referrals did occur before the Internet and before e-mail. They'll go on.
