Need help in building app for finding & sharing cool products

I’m working on a mobile app that allows discovering & sharing of cool products (Electronics, gadgets, video games, gears and etc).
I’m really hoping to ask you guys few questions that will really help me shape the app and it’s content.

Feel free to refuse, but if you are willing to help me, you can either pm me through the forum, register at our launchrock page (http://brixter.launchrock.com/) or contact me directly.

Thanks a lot.
