Actually, there are soooo many social news community in the internet. Digg and Technorati maybe the most popular, but I’m gonna tell you about a social news community called IMCurtain. It has same concept with Digg or Technorati, you can submit your articles and drive more visitors to your blog.
It’s still adopting vote system, it means users can vote all the articles in IMCurtain, just vote up or down. IMCurtain has also Live viewer that makes us possible to watch the queued news updates. It also uses Karma to show the level of users, if your Karma grow higher you will be added as top contributors.:P
Ok, that’s it! I think it would be better if you try it by your self.
