Ah, right–I managed to miss the lack of “My Documents” at the end of the “home directory”! I blame lack of sleep! ^^;
However, I disagree with the idea that “My Documents” would be the “home” directory: are “My Pictures” and “My Music”–which should be within the same directory as “My Documents”–not part of the user’s “home space”, so to speak?
Additionally, I don’t know how others use it, but I tend to use “My Documents” specifically for storage of… well… documents: text-based documents (text files, pdfs, LibreOffice files, etc.). I don’t think that I’d expect to find game files in “My Documents”.
To my mind the parent directory of “My Documents” would indeed be the “home” directory, not “My Documents” itself.
