The old LessWrong wiki was a companion wiki site to LessWrong 1.0, it was built on MediaWiki software. As of September 2020, the LessWrong 2.0 team is migrating the contents of the old wiki to LessWrong 2.0's new tag/wiki system. The wiki import is complete.

This page contains the list of all pages that are being imported. Imported page fall into one of three types:

• Imported as a new tag page that can be applied to posts (76 pages).
• Merged with an existing tag. The revision history of the old page is copied across and manual merges of the text are required. These manual merges are underway. (111 pages).
• Imported as "wiki-only", these pages appear like tag pages except that cannot be applied to posts. Admins can change the wiki-only status of pages. (386 pages).

Note, some of these pages were since deleted or merged, so surviving totals may be slightly lower.

Further details of imported pages, included state of clean-up work, and links to the original pages can be found in the Wiki Import Spreadsheet.

Import Philosophy

The goal is to fully import the contents of the old LessWrong wiki and eventually turn it off. To do that, we must fully preserve any substantive content from the old wiki, even if it is a strange fit for the new wiki. We have erred on the side of being inclusive rather than exclusive, and some pages might seem weird. That was intentional.

Pages Imported as New Tags (76)

The following pages from the old wiki have been imported to LW2.0 as new tags that can be applied to posts just like any new tag on LessWrong.

Pages Being Merged with Existing Tags (111)

These pages are being merged with existing LW2.0 tags that are about the same concept.
This involves two steps:

1. Import the revision history of the page from the old wiki and prepend it the history of the LW tag. On the tag page click "History" to view these imported revision histories.
2. Manually merge the old and new texts of the page by combining them into one new "super page". This step is getting underway and we're looking for people to help us out. You track progress on pages that need to be manually merged on the Wiki Import Spreadsheet.

Pages Being Imported as Wiki-Only (386)

These pages are being imported as wiki-only. They cannot be applied to posts as tags. 

We decided that many of the pages are not suitable as tags for one more reasons, such as 1) the concept covered is not notable enough 2) the concept covered overlaps heavily with another existing concept, 3) the page does not cover a "concept" in the usual sense. To expand on the second, I think it would reduce the usefulness of the tag system if a post had 3-5 extremely similar tag, or each time someone searches for tags to apply, 3-5 extremely similar tags pop-up. Better for there to be one tag per "cluster" which in turn links to multiple other pages.

However, changing a page between tag and wiki-only is only a checkbox. The moderators reverse decisions we've made here easily if it's clear we've made a mistake. Ping us if you think we didn't choose right!
