ChinaSMACK.com has to be one of my favourite sites on the net. Fauna, the site's creator translates posts from the Chinese language Internet. Topics always give a fascinating insight into Chinese culture. She usually links to the original forum too. A word of warning though, most material is really really difficult Chinese; think of the slack grammar/spelling that you use when posting in your own language, and think of how difficult it would be for a learner to understand. Tthis is why it's so hard.
But even if you don't bother having a look at the original posts, and only read the English translations at ChinaSMACK.com, you will find it interesting.
