I have a big picture view to eventually build a community with trust where students, family, and friends could have more interactions and networks to attract more new users join it. To do this, challenges will be on:
1. Referring system, how can we make users share the good news by different contacts, how can we make users buy things and send gifts easily.
2. Privacy system, how do we balance users on what they want to share and what they don't want to share with the public.
3. Game/promo system: creating more promos that stimulate users to interact more with their family or friends.
