Wording inconsistency:
Accomplishments are referred to on one's profile page as "Badges", but are referred to in some quests (one I remember was the "Learn to milk a butterfly" one) as "Achievements". Took me a while to figure out that the "Butterfly Whisperer achievement" (which Pet Rock called it for that quest) could be verified by looking at my Badges. I'd been searching for a list of which achievements I had. (Duh.) A simple wording change would fix this.
