The thing is, "human readable" files aren't, once they get to a nontrivial size. Picking apart a megabyte XML file in a text editor is arguably harder than the same data as a blob in a hex editor.
In fact, thinking about it now, I bet Wireshark would be awesome for that.
Eh, once you're used to reading integers in hexadecimal, byte order isn't that important. If I told you that 1234 was going to be written right to left, you'd know how big 4321 was, right?
