Greengas, I have always believed that his primary role on that board, whether it be of his own or of other's intent, was to increase click-rates throughout the site and therefore increase ad revenue.
Of course, sometimes I also wonder if he (or they) are trying to purposefully clutter up the board so that normal retails are not able to find much information, therefore trying to keep Connacher from attracting much attention.
There are obviously hidden forces at work behind his intentions, whatever they may be.
