I also created a intro youtube video to go along with the launch:
I read a handful of articles on how to have a successful launch, and some advocated practices that seemed unethical: manipulation and transactional networking (e.g. using people for their network or votes). And I've had 2 offers from "digital marketers" who offer to boost my PH votes. No thank you. It may not be the best decision for my product but I'm going to keep it all organic. What do you think about the pressure to gamify PH and sites like it?
