Today someone send a new site to me http://scoopea.com/ ,at very begining i don't want to click it,because every site like digg are boring ,but after my visited it that changed my mind, it's quite usefull for life... it have more great link for talking around life. I submit alot in this website,and get alot traffic back.but when i check the PR,it's no any PR. i don't know sites have big traffic without PR. hey friend you should try it, whatever you don't need pay!
