I'm trying to look at things from the point of view of an outsider.  Yes,
there's LOTS of laborious maintenance to be done, but the newbie doesn't
see this (due to the immense amount of testing in the immensely long
release cycle).  Emacs DOES need new features (refactoring, better
browsing, etc.), but those are rarely obvious to the new people we need.

It's more of a long term problem, in that the number of Emacs users might
be gradually declining.  I'm only guessing here though, I don't know.

Er, I never meant them to be.  I was throwing around some ideas for
discussion.

Yes.

HEY, THAT'S NOT FAIR!!!!  You've distorted my post by selective deletion.
When I said CVS was good, I qualified clearly what I meant by reference
to hammers, nails and screws.  The steam engine was a wonderful invention
too, but no modern railway system would now deploy one as prime choice of
traction.

And no, I don't think I ever have used a good VCS, and you and one or two
others have just made me aware that I'm missing something worthwhile.
Cut me some slack, please.

OK, here's where you need to persuade me (?us).  There have been lots of
bugs in CC Mode where I've had to dig myself in without distractions for
hours at a time, sometimes days, to resolve; bits of Emacs are like that
- some hackers are like this.  I've been able to emerge and engage in the
mailing list.  I don't think I could do this with a rapid-fire IRC
instead of email.  Richard has said he couldn't spare the time for this
style of hacking.  I believe him.

It seems that there will be losses as well as gains from moving to IIRC.
How convinced are you that the gains will outweigh the losses?  Is there
perhaps a third way which combines the good bits and minimises the bad
bits of the other two?

A web browser is for browsing the web, and is pretty cruddy for anything
else.  For email you'd use mutt, for documentation C-h i, for usenet tin
or slrn, and so on.  Surely there's a purpose built tty client for IRC.
