Academia.SE users (myself included) have been known to make edits to other users' posts that are merely a matter of style. For example, edits that:
- Add semi-colons to the end of list items. For example, see revision 3 on this post
- Remove a "Q" denoting beginning of question. For example, see revision 3 on this post
- Add question mark at the end of question title. For example, see revision 3 on this post.
- Add clickable links to widely known sites (already discussed here)
- Add 'quote' formatting to quotes, e.g. revision 2 of this post
- Add full citations for links that are given as URL, e.g. revision 2 of this post
- Add full citation for links that are given inline as clickable text, e.g. revision 4 here
- Capitalize acronyms like "IEEE" or "DOI", e.g. revision 4 of this post
- Capitalize 'Phd' or 'phd' to 'PhD', e.g. revision 3 here
- Capitalize (only) first word of title, e.g. revision 3 here
- Break up wall-of-text posts
It is my opinion that some of these edits are generally useful; some are useful only if you are anyways making more substantial changes to a post at the same time; some are useful only if it doesn't involve bumping an old post; and some are not useful at all, or even annoying to some users. However, I think it's hard to tell which edits fall in which category.
What are some guidelines for users to determine whether to make an edit that is purely a matter of style, as in the examples above? How, specifically, would these guidelines apply to the examples above?
This has been discussed on main meta, but only with regard to style of code snippets. There, the consensus seems to be that subjective style changes to code snippets are inappropriate.
