I don't think its a good idea to teach or insist that people adopt
emacs's terminologies.

In particular, the term buffer is unsuitable and outdated. See the
following argument:

----------------------------

Q: The Terminology “buffer” and “keybinding” is good as they are.

A:
The terminology “buffer” or “keybinding”, are technical terms having
to do with software programing. The term “keybinding” refers to the
association of a keystroke with a command in a technical, software
application programing context. That is to say, a programer “bind” a
keystroke event to a command in a software application. The term
“buffer” refers to a abstract, temporary area for storing data, in the
context of programing or computer science.

These terms are irrelevant to the users of a software application.

As a user of a text editor, he works with files. The terms “opened
file” or “untitled file” are more appropriate than “buffer”. Since
emacs is also used for many things beside reading files or writing to
files, for example, file management, ftp/sftp, shell, email, irc etc.,
the proper term can be “panel”, “window”, or “work area”. (All modern
editors and IDEs use these terms, even though they are all buffers
too)

And, the term “keyboard shortcut” refers to typing of a key-
combination to activate a command. It is also more appropriate than
“binding” or “keybinding”.

Although concepts like “buffer” and “keybinding” are seemingly
interchangeable with “panel” or “keyboard shortcut”, but their
contexts set them apart. This is why in all modern software
application's user documentations, terms like “buffer” or “keybinding”
are not to be seen but “windows, panes, tabs, workspace, and keyboard
shortcuts”.

The reason emacs uses the technical terminologies throughout is
because when emacs started in the 1980s, there really isn't any other
text editors or even software applications. And, emacs users are all
computer scientists and programers.

Note that Emacs does officially recognize the term Keyboard Shortcut.
The following is a excerpt from glossary section of the official emacs
manual from emacs 22:

Keyboard Shortcut
     A keyboard shortcut is a key sequence (q.v.) which invokes a
     command. What some programs call "assigning a keyboard shortcut,"
     Emacs calls "binding a key sequence."  See `binding.'
