Gamification is good to initially gather a community but eventually you supposely want millions users in your platform and gamification isn't enough of course
No it is true. To get millions of users you need to deliver a honest, seamless, and accessible product, being accessible, very transaprent, and with a charismatic team.
Transparency is nice but it is not an necessary to get millions of users. Quite the contrary, actually. Nobody needs or wants to know all the details of a platform except for the investors and the few of us here. After launch, the average user doesn't care about a charismatic team either. Can you name anyone that is on the board of The New York Stock Exchange? I can't. I don't know who the CEO of Coca-Cola or McDonalds is either but I know how much a hot & spicy McChicken sandwich is. To get millions of users, you need a product that works better than the rest. UI is of the most importance next to functionality. I think you guys are doing great by the way.
