I'm planning on going "out of the building" very soon and go talk to some potential users, so the part about refining the opening phrase is very useful. It won't be cold-calling but going to talk to people on the street so I'll be interrupting them somehow, so I'll have to pay attention to what works and what doesn't… On the "this does not scale" part, this is a recurring theme: Alexis Ohanian commented with multiple accounts at the beginning of reddit, IIRC Facebook was getting the class schedules more or less manually, Airbnb's CEO slept at many people's homes to understand their needs, I believe the guys at Quora were answering questions themselves, etc. This doesn't scale but it gets things moving and you learn what really works.
