For me, these things will get my attention on social shopping site: 1. what my friend bought recently. human being has curiosity. 2. what is running hot in my local area. 3. I want to buy something, but, instead of doing intensive research online by myself, I'd like to see what people say about it. I will give higher weight for what my friend say, then what people has similar background like me say, and then total strangers. Harry
