> the vast majority of people [..] believe backslashes are the way to go
Not sure you got that right. I'm certain there are more people that use forward slashed in a browser (every OS+mobile) than people who type backslashes in Windows.
My mother has used Windows for years and doesn't even know where the backslash character is. She can type URLs though.
just some feedback: I got stuck in the tutorial at "Give a title to your map." - it just sits there and won't go away (no next button). yes, I gave it a title.
