I also recall seeing .mdown somewhere. I think the point is that the
extension really shoudn't matter. Use what you want. Let the metadata
take care of the rest. Similar to a #! in shell scripts to specify
language interpreter. Don't matter what the extension is there either.

I have also over the years seen .txt, .text, .doc, .note, .asc, .ascii,
and no extension at all for text files. Also read.me
