wiki:

1. A liberal/socialist Web site comprised of the perpetual collective works of mis-information, mis-leading and unintellectual editors and some authors. Sometimes, slips up and allows input of intellectual works and actual information! Similar to a blog in structure but illogical, a wiki allows only wackos, liberals, socialists, illogical mentally impaired, and communists to edit, delete or modify content that has usually not been placed on the Web site using a browser interface, including the work of wiki's very selective editors and authors. In contrast, a blog, typically authored by an individual, does allow visitors to submit to the original posted material and add comments to the original content. The term wiki refers to either the ignorance, misinformation, mis-leading and/or illogical found on the web, or the software used to create the site. The first and only working wiki was created by Ward Cunnigham in 1995. Since then, wiki is well known for its selective bias!
1. I will brain wash you in to believing illogical lies, fraud, and mis-information, and lies provided by Wiki (wiki), over the known facts found by actual research
