On a number of occasions I've noticed that users make minor edits to questions I ask. I can understand edits for spelling, grammar, code formatting etc, but I'm surprised to see so many edits for minor differences in writing style. So, I'm wondering what reasons there are to make very small edits to questions. Reputation? Something else?
A recent example is here (though definitely not meaning to single that user out): https://unix.stackexchange.com/posts/219889/revisions
I have no issue with people editing my posts, just wondering if there's a subtlety of the editing process that I've missed.
