Blog pages are wiki pages like any other, except that they are framed so that they have only one author. Edits are typically of the non-substantive variety -- that is, edits for formatting, grammar, layout, wikification are accepted, but changes to the authors tone or thesis are discouraged. Blog articles make it to the top of the blog homepage -- Special:ArticlesHome -- when they receive a certain number of votes and/or unique commentators commenting.
