Here is the website link that shares Adsense revenue

XiTalk stands for "Extreme Intelligence Webmaster Talk", this community has a lot of potential and offers to share revenue among its members. What their system actually does is displays 50% of the Google Adsense by the topic starter and 50% from the XiTalk, fair enough. This way you havce 50% chance that your ads will be clicked.
How does this work ?
Basically you have to register at XiTalk.com and set your Google Adsense publisher and channel ID, after that you post an interesting topic, if you don't have any interesting topic just start asking questions about any topic, Google Adsense will display relevant ads into your topic at 2 locations, so if the topic is read by many users you have a lot of chance that your ad will be clicked. Revenue sharing has become so popular and people at XiTalk are already making money. For more details, visit their website at
