How am I supposed to name readme files? My first inclination is all lowercase, .md. Most are capitalized. Some are .markdown. I have a soft spot in my heart for textile, but does anybody use it anymore?

What does everybody else do? Here are the simplest possible statistics I can grab through github’s search. (It doesn’t discern upper from lower case, which is a bummer.)

{README,Readme,readme}.{md,markdown,textile,…}

# extension
7,061,887 md
386,111 markdown

TODO: how can I search by case? I’d love to know if README beats Readme or readme.
