Given that
- there are different rules for the capitalization of words in headlines, e.g. for newspapers; here is randomly chosen link to some rules
- there are no related styleguides for MO
I would localize the preference of one rule over the other in the realm of personal taste or opinion and would like to learn how others think about the benefit of edits that primarily change capitalization according to one's personal preference; should these edits be welcome or deprecated?
Regarding the convention for up/down-voting the question: let upvotes mean that edits motivated by personal preference should not be made and down votes that those kinds of edits are ok
