We certainly don't think maps or Top 10s are 'bad' features - but spreading our resources too thinly across different features means they can't all get the time they deserve (Bert covers this a bit more below). Top 10s have always been pretty niche (and a little odd), and we don't dislike them - but it's a situation where resources are probably best spent elsewhere on other more effective contribution features.
