I asked this question when emacs 21 was current and if I recall there
was some horribly complicated (requiring coding and good knowledge of
elisp) way to do it.
I wondered if with 22 or even 23 one can write the \*Messages\* buffer
to disc as a session progresses any easier than before?

I vaguely remember that thread, but I couldn't find it on the web. In
any case, I think it's not too complicated (everything worth doing in
Emacs requires a basic knowledge of Emacs Lisp):
(setq message-log-max t); Emacs Lisp!!!
(with-current-buffer (get-buffer "*Messages*")
(setq buffer-file-name "~/.emacs_messages")
(setq buffer-offer-save t)) ; just in case
(defun save-messages-buffer ()
(with-current-buffer (get-buffer "*Messages*")
(save-buffer 0))) ; or just (basic-save-buffer)
(add-hook 'pre-command-hook 'save-messages-buffer)
(add-hook 'post-command-hook 'save-messages-buffer)

[...] snipped the nice example... thanks.
Nice... thank you. I have to beg to differ on one point and I'm sure
you meant no harm with it...

Not so... I have only a vague knowledge of emacs lisp and have managed
to use emacs in useful ways every day (or nearly so) for at least 10
yrs. Much to the chagrin of this list.. I imagine,ue to the
ill-informed questions I've often posed here.
I always think I'm going to take out the time to learn some elisp but
have just never done it. Its not really due to laziness or at least
not only laziness either. Seems something more immediate always comes
up.
Further I haven't found a nifty way into the learning part like I have
with perl or shell scripting where I've needed to learn a little of
each to admin my home machines and my videography (hobby/business).
In those cases, with a basic knowledge of shell scripting I've been
able to learn a fair bit of perl by seeing code and asking lots of
questions. ... not so with elisp.
The question part never fails on this list, but I've never been able
to look at the code and sort of start to see how it works. Then sort
of ease right into useful coding.

Probably a future Emacs will have video-editing support; hopefully
the code posted re those issues will be more engaging to you.

This behaviour is not that useable as it constantly clutters the
minibuffer with the message "Wrote ~/.emacs_message". Can we make save-
buffer() silent perhaps?
It also writes to disc every time every time we navigate in the source
code which I believe is not that good for performance. I believe a
better solution would be to auto-save the buffer reguarly using a time
interval. Somebody know how?

You can use the run-with-timer function. Here's a example snippet:
; record opened files (session) every 5 min
(run-with-timer 600 600 'desktop-save "~/")

That message comes from write-region, which fortunately provide a way to
silence it:
(defun save-messages-buffer ()
(with-current-buffer (get-buffer "*Messages*")
;; (save-buffer 0) or even just (basic-save-buffer) is too noisy, so
;; we lose their functionality (including basic-save-buffer-1 and
;; basic-save-buffer-2):
(when (and buffer-file-name
(buffer-modified-p))
(write-region (point-min) (point-max) buffer-file-name
nil 'quiet))))
