I know I've used it, to find, research and understand the layout of, Actual Locations on Earth, more than once. I never even stopped to think about the projection.
It would be interesting to hear what you feel would be different in the end-user experience if the projection was changed.
De-zoom and look at the apparent continent sizes, it's just horrible. Half of emerged lands in antarctica ? Groenland the size of Africa ? Think about children exposed to those maps before a good atlas is showed to them.
I co-wrote a paper about this topic, but it's in french :
A technical choice (summary : it's easier to have perpendicular parallels and meridians) has prevailed upon a geographical choice. It's not very complicated to link the projection to the scale of the view, all serious geographical internet portals are doing so (IGN, Ordnance Survey, etc.)
