I noticed someone recently edited one of my answers (along with the question for which the answer applied). The only edit this person made was to change the word 'wifi' to 'Wi-Fi'.
I understand that the wikipedia entry prefers 'Wi-Fi' as the proper terminology, but it also says it can be spelled 'wifi' (as well as 'WiFi' [no dash]).
Editing an answer simply to change wording is questionable at best, since the editor is not actually clarifying anything with the edit.
And I would argue that it makes the question and answer worse, because almost anyone would first search for 'wifi' before trying 'Wi-Fi', if they even think to search for the term with a dash at all. I tried a search with just 'wifi', and the question and my answer no longer show up.
Should these edits be reversed? Or does it make sense to change all 'wifi' to 'Wi-Fi'? If the latter, could the search engine be revised to smartly search both terms?
I do realize that the preferred 'tag' in SE is 'wi-fi', with the dash. However, I think most users will search for 'wifi', no dash.
