Right now it only works on LessWrong...
Correction

OpenErrata did not "only" work on LessWrong at the time of the post; the project’s own README (from Feb 22, 2026) lists support for X (Twitter) and Substack in addition to LessWrong.

Full reasoning

The post (published 2026-02-22) says: “Right now it only works on LessWrong...”.

However, the OpenErrata GitHub repository’s README at a commit dated Feb 22, 2026 includes a “Supported Platforms” table listing LessWrong, X (Twitter), and Substack as supported platforms. That means, as of the same date as the LessWrong post, OpenErrata already supported at least these additional sites—so it was not accurate to say it only worked on LessWrong.

To verify the timing, the GitHub commit history shows commits on Feb 22, 2026, and the README content at commit 1840758 (a Feb 22 commit) contains the supported-platforms table including X and Substack.
