I used the Wikipedia layer extensively during a road trip around Scotland. It was a great way to find nearby places of interest - I daresay the trip wouldn't have been anywhere as interesting without it. More recently I was in France, hoping to do the same thing. To say I was disappointed to find the feature had been removed is a massive understatement.

I don't really understand how Google gets away with this sort of thing, I thought it was Software 101 to never remove features. It's sort-of understandable if the feature has very few users, but it sounds like this one is used by quite a lot of people.
