OTHO, vanilla Emacs could add a tiny guide like I proposed to more or less
improve the life for those who started Emacs without reading any tutorial on
the internet.
Sorry to be negative, but based on experience I have hard time
believing in such guides: people who are involved in Emacs development
are much better coding than writing good documentation, let alone
tutorial documentation for newbies. Let's do what we do best: produce
features that make it easier to discover and turn on popular features.
