My focus is entirely on referrals - toward that end I research referrals and share that information in several ways:
Referral Triggers is one -- and it's a differentiator.
Referral Triggers are not icebreakers, or elevator pitches; they stimulate thoughts in the listener, because all referrals start in the listener's mind. In the particular case of Referral Triggers the thoughts are "what is like, and what is not like, what I'm hearing." One way to capitalize on this is the opportunity to show the answers Referral Trigger questions on each Member's profile page.
Action > Answer. Reaction > Thought. Result = referral.
