I agree.

Thanks for sharing that link about Google. I'll add it to my page
of Google Bugs at http://mjr.towers.org.uk/blog/2006/google

Arguably, irreversible actions should have a confirmation page
to avoid the problem of wild-clicking and then hitting the
wrong dialogue box button key. So, ultimately, it would meet
your recommendation to use a POST for the destructive part.
(Arguably, destruction should be an HTTP DELETE but damned
if I know how to make today's browser send that.)

If the icons were both image and text on a standard base
button background image(s), it could:
1. make templates easy to translate because there is nothing
to translate in the images;
2. make templates easier to re-skin, simply by replacing the
background image and stylesheet, without messing up the
translations;
3. maximise the space users can click on, which is good for
Fitts's Law: The time to acquire a target is a function of the
distance to and size of the target.

Hope that helps,
