None? Why is 'social' stuff so cool this days? I still strongly believe word of mouth is the best way to share what you believe is worth showing. When you browse the internet you are constantly bombarded with things a friend of a friend of a shared that you do not really care, but if someone you trust told you personally to check out a website, the you check the fuck out of that website. Therefore, is a social integration really needed? If so, why?
