Too late now, I suppose, but the only file extension I would endorse is “.markdown”, for the same reason offered by Hilton Lipschitz: We no longer live in a 8.3 world, so we should be using the most descriptive file extensions. It’s sad that all our operating systems rely on this stupid convention instead of the better creator code or a metadata model, but great that they now support longer file extensions.
