The 100 Most-Edited Wikipedia Articles | FiveThirtyEight: Not surprisingly, Bush isn’t the only political figure to attract factual controversy. The Wikipedia entry on Barack Obama has been revised 23,514 times — just slightly ahead of Adolf Hitler (23,499 revisions). Ronald Reagan, Abraham Lincoln and Bill Clinton all make it into the top 100 (Sarah Palin falls just short, in 104th place).
Articles on religion, including Jehovah’s Witnesses and Muhammed, or about specific countries, such as the United States and Israel, attract plenty of revisions. More surprising, however, is that World Wrestling Entertainment (WWE) features in more revised articles than any other single body — seven — and is responsible for the second-most-revised article: list of WWE personnel.
