In a meeting room in DJI HQ sometime ago...
Guy A: I'm thinking of ways to market the Phantom in a more social way.
Guy B: Hey ppl come up to me all the time and ask about it when I fly in parks.
Guy A: Then we should give incentive if that happens to our customers, maybe a free battery?
Guy B: Yeah! We can do that by a special website. Give them QR codes to go there!
-- boss walks in, asks what's up --
-- Guy A and B explains their plans --
Boss: Incentives? Meh. These things practically sell themselves. Print cheap business cards if you want, but that's all I'm giving you. Now get back to work.
