Bidirectional referrals were a crashing failure for BCC, the one time I implemented it. I also don't like the interaction that makes my customers have with their friends, particularly not in a B2B context. (I mean, wouldn't it put an undesirable thought in the back of your head reading my stuff if you had to wonder every time you heard me say, e.g. "Twilio is the best thing since sliced bread", whether that was being tracked and compensated?)

P.S. A lesson I learned early in AR's career: don't call massage therapy practices "massage parlors". That is one of a couple of word choices which massage therapists are really really touchy about: http://www.massagetherapy.com/articles/index.php/article_id/...
