Well, it matters to me. At least when I see people that I *know* will
benefit from using Emacs.

I don't have to look far. At work, there's people doing daily tasks
with Perl scripts and a very old (circa 1985, perhaps older) non-free
MS-DOS text editor, MultiEdit. If they used Emacs (and a couple
hundred lines of elisp code I could write for them), they would save
*lots* of pain (believe me when I say that: I wrote the Perl scripts
and know pretty well the data workflow). But there's no way in the
world that they will invest the time to adapt to Emacs, because it is
too far removed from what they're used to. In despair, I've even had
pipe dreams of writing a limited emulation of MultiEdit 3.0 in Emacs
22.

Their fault? Of course. Still...

Sorry if I offended you. What I meant is that whether people will
contribute or not bears no relation to whether we should try to make
Emacs easier to learn or not for newbies.

You won't see me defending that choice, though FWIW I think that's
Apple at work, not Microsoft.

I know.

Window vs. frame is an example. Not that I'm proposing changing it, of course.

Yes, it makes sense, but it was stretching a metaphor (even if it
predates Emacs). Moreover, I see two partially contradictory defenses
of "buffer":

  - that it is obviously a good term, whose meaning is quite easy to
grasp from previous meanings
  - that it is a concept more-or-less specific of Emacs and so it
helps newbies to realize that they are not dealing with files or
workspaces or anything like that.

Curious. I wouldn't consider stability as *the* defining factor of
Emacs buffers; temporary buffers are about fast, non-persistent
storage, not stability, for example.

I think that's conflating the program's view of buffers with the human
one. I've never thought of buffer's contents as messages, and they are
not FIFO queues for data.

According to current trends, Firefox. If we started Emacs from
scratch, I bet we would call the frame "window", and the windows,
"tabs" (or "panes", depending of the specific details of the user
interface).

Do you find difficult to use Windows (if you use it at all) because
the directories are, from the desktop POV, called "folders"? I'd bet
the answer is not, still you joked about because you think it is the
wrong term.

As opposed to the terminology we use now, that has not become
outdated, you mean?

I'll abstain.
