Not typically.  Byte-compiling pays off when code is evaluated many
times.  The lisp in your .emacs is typically executed only once.

Besides, it's not worth your time you'll lose someday when you'll edit
the non-compiled version, expect a change to happen, and you'll forget
to re-compile it, and wonder why your change didn't have any effect.

try it out and you'll never forget to re-compile:

(defun autocompile()
  "compile itself if ~/.emacs"
  (interactive)
  (if (string= (buffer-file-name) (concat default-directory ".emacs"))
      (byte-compile-file (buffer-file-name))))
(add-hook 'after-save-hook 'autocompile())

Beware: this doesn't take into account those platforms where the init
file might be called "_emacs" instead.

... however it works on:
-linux
-cygwin (windows)
-native windows
no matter its a tty or x11 (motif,gtk2)

The Windows port allows the init file to be called _emacs; some
Windows users think (incorrectly) that file names with leading dots
are not allowed.  Your code will fail for such users.

Is it so hard to make an allowance for "_emacs" that you are so
motivated to reject my suggestion?

Why don't _you_ just add the required code and stop complaining?

It just doesn't make sense for Eli to add code to Niels' ~/.emacs
file.

As long as Eli is the only one complaining, I think he should.

I didn't complain.  I made a suggestion for improvement, based on my
experience with different non-Posix systems.  If my suggestion is not
to someone's liking, feel free to ignore it.

Make after-save-hook local in that buffer and the test can disappear. 
For example, I have:

;;; Local Variables:
;;; after-save-hook: ((lambda () (byte-compile-file buffer-file-name)))
;;; End:

You also lose portability between linux/gnu emacs and xemacs,
as well as other versions of *emacs.

If you have written any major editing commands try putting them in a
separate file, byte-compiling this file and loading it in .emacs . 
This keeps them away from configurations you may change often.  As
others have said theres not much to be gained though.
