Thread:Talk:MediaWiki/The intro doesn't say what the software is used for

"MediaWiki is a free software open source wiki package written in PHP, originally for use on Wikipedia. It is now also used by several other projects of the non-profit Wikimedia Foundation and by many other wikis, including this website, the home of MediaWiki."

Thank you, but that intro says zero about what the software is used for. I think the intro ought to have some overview of the purpose(s) of the software.
