This article does not adequately introduce its subject or stand alone

@Fgnievinski – You copy-pasted the middle of another article as the lead of this one. It doesn't work; the content fits in okay as a section there, but as a lead it does not adequately introduce the context or explain what the subject is. This lead needs to be completely rewritten so that e.g. a non-technical reader who ends up here can get a basic idea of what it is about. I removed the "excerpt" on the other article, because if at any point someone writes an even basically adequate lead here, it will no longer be appropriate as a summary in the context of the middle of another article.

(Aside: This is the fundamental problem with the "excerpt" feature, and why it should be avoided to the extent possible; it inherently promotes mediocrity.) –jacobolus (t) 15:20, 17 May 2023 (UTC)[reply]

I tried to do a quick rewrite, but this is still not amazing (in particular, is pretty dense on jargon and thus not very friendly to non-technical readers). –jacobolus (t) 17:03, 17 May 2023 (UTC)[reply]

Also the content here is almost entirely unsourced. Can you try to track down some high-quality references? I have plenty else I'm working on and don't immediately need another research project. –jacobolus (t) 17:02, 17 May 2023 (UTC)[reply]

Agree, I've tagged the article with template:lead rewrite. A separate article, however in progress, is much better than having this notable concept buried in Angular displacement, which is a much simpler concept. Automatic excerpts is an economical way of avoid duplicates across Rotation (mathematics), 3D rotation group , Rotation matrix, etc. fgnievinski (talk) 17:31, 17 May 2023 (UTC)[reply]

The automatic excerpts are "economical" in the sense that they save a few bits in database storage somewhere, but they are a mediocre result for readers and they discourage improvements from other Wikipedians. Just plain copy/paste is better in pretty much every way. –jacobolus (t) 18:56, 17 May 2023 (UTC)[reply]

Automatic excerpts are widely used, appreciated, and recommended: Wikipedia:Summary_style#Using_excerpts_for_article_synchronization. fgnievinski (talk) 01:18, 18 May 2023 (UTC)[reply]
