well, it depends on what type of comments you guys find acceptable & would want to see when you're deciding whether to merge the changes in.
imagine down the line somebody submitting changes & the message isn't the reason why those changes are there[0] but instead a copy paste of the changes[1]
[0] e.g. "remove fuzzy language"/"update intro to more accurately reflect addition of new services"
[1] not denying that sometimes this makes more sense.
Something like that change should have a message explaining why that change is proposed.
Unfortunate that the blogpost itself can't be forked :p
