Extension:LiquidThreads

LiquidThreads is an extension that implements a new discussion page system. The original code was developed by David McCabe under sponsorship from the Google Summer of Code 2006, the Commonwealth of Learning, and Wikia. However, David McCabe is no longer involved with this project. It is currently being developed by the features team at the Wikimedia Foundation.

Status
The original LiquidThreads code has been substantially improved and augmented by Andrew Garrett at the Wikimedia Foundation since May 2009. In January 2011, a new re-engineering project was begun at the Foundation, and it is anticipated that this will result in a pilot on a large project by the end of Q1 2011. An older version of the extension is also in testing on several MediaWiki sites, and was used in the strategic planning process.

Rationale
Wiki discussion pages have some advantages over web and Usenet forums. They allow use of the entire wiki syntax - from images to wiki links to transclusion. It is possible to refactor entire discussion pages.

Web forums offer a number of advantages over the MediaWiki talk page model:
 * Threads can be displayed in different views: flat, nested, sorted by date, subject, etc.
 * The user only needs to click a "Reply" button or link in order to respond to a comment. Manual indentation is not required. Quotations from the source comment can be inserted automatically.
 * Comments are automatically signed and dated.
 * Avatars are possible. (but not yet created)
 * The user can watch individual threads or be notified about responses in threads.
 * Comments and threads can be displayed individually, without the surrounding page.
 * Old comments are archived automatically and invisibly, with permanent links easily available.
 * Search for author, subject, date, etc. is possible
 * Individual threads can have categories.
 * It is relatively easy to manage related discussions in a subject-specific forum, whereas MediaWiki talk pages always follow the "one discussion page per content page" model.

LiquidThreads aims to unite the advantages of both forum types, and to add some unique discussion features to boot.
