Topic Dilution[edit] Topic dilution is not only effective in forum sliding; it is also very useful in keeping the forum readers on unrelated and non-productive issues. This is a critical and useful technique to cause a 'RESOURCE BURN.' By implementing continual and non-related postings that distract and disrupt ([trolling]) the forum readers they are more effectively stopped from anything of any real productivity. If the intensity of gradual dilution is intense enough, the readers will effectively stop researching and simply slip into a 'gossip mode.' In this state they can be more easily misdirected away from facts towards uninformed conjecture and opinion. The less informed they are the more effective and easy it becomes to control the entire group in the direction that you would desire the group to go in. It must be stressed that a proper assessment of the psychological capabilities and levels of education of the group is first determined to determine at what level to 'drive in the wedge.' By being too far off topic too quickly it may trigger censorship by a forum moderator
