Like I said, customer-specific advertising is effective...until a certain point. Personally, this creeped me out:
The data provides enough information to provide a fairly strong estimate even without customer input, [Danny Kennedy, head of Sungeivty] said. To prove its point, Sungevity is going to mail fliers to all of the homes in Albany, Calif. Each flier will come with a picture of the home that goes with the address on the flier, a picture of the home with simulated solar panels, and the cost savings. (To fine-tune the estimate, customers need to submit their power bills.)(Article, here)
How would you react if you got that in the mail?
