Wikilog enhances MediaWiki with some common blogging features, making it a wiki-blog hybrid. There are many names that are used to represent this concept: wikilog, wikiblog, bliki, etc. (see Bliki article on Wikipedia).
The philosophy of Wikilog is not to just make a blog out of a wiki, but to combine both concepts. Unlike most blogs, wikilog articles can be collaboratively written and published by multiple users. Talk pages of wikilog articles provide a simpler interface for commenting than standard MediaWiki talk pages; it is similar to most blog software, with the addition of discussion threading.
