Wiki Wiki Where is the Wiki?

If the purpose of a Wiki is to develop and build a breadth of knowledge from various members of the Internet International Jet Set in regards to a given topic, why is it that much of what I visited seemed to have no rhyme or reason in regards to adding facts that develop the body of knowledge? In addition, many of them asserted opinions and a list of ideas or better yet running logs on given topics. No wonder I haven't spent much time on looking at this technological avenue. I will give credit to the person who developed the Wiki for which I am posting a link. It is a nice resource, but there is no body of knowledge that supports the reliability for the suggestions and ideas shared as actually developing the knowledge of a child in regards to the terms and ideas often found or discussed in children's poetry. There is no structure for the development and implementation of how to teach poetry to children although some of the links provide ideas for doing just that.
