Wiki Schizophrenia
Over time, a paragraph—nay, an entire article—has collected enough disguised discussion and entry pimping that it no longer makes sense to those poor, benighted humans who are mired in the muck of the pre-wiki English language. It argues against itself, in a private language that is rich in secret words, an argument full of terms that must be read in another browser tab if there is any hope of following the first item.
Poor reader. Sometimes even those terms' definitions are likewise insane.
Wiki Schizophrenia can refer to the way the article appears, or what it does to the reader. Compare Justifying Edit.
