I wonder if the major Atom users are working with nicer repos than those who lament that they can't use it. The ideal project would maybe be a max of 3 or 4 levels deep (but fewer in most part) with 5-20 folders/files in each folder, and most files less than 200 lines and all less than 1000 lines. A lot of repos are not like this though - they have too much crap in them.
