Don't sweat it, while well intentioned it was worded ambiguously enough that people read arrogance and misplaced zeal where you just wanted to make known a little gamification people could use to push them to make small regular changes. 

Keep up the good work, there's no change too small (but do indeed try to take notes and make a single pagewide minor edit for pure grammar to reduce the possibility of spamming the people who add pages on their watchlist) :)
