recently (as of 2005-12-23), Matt Brett created a reproduction of the standard feed icon (now used by Firefox and soon used by IE 7) in a diverse array of formats.
seeing this standard being created, I am slightly irked by Safari's use of a simple 'RSS' icon.
Safari's default icon.
New standard feed icon.
I don't blame Apple; the feed icon hadn't yet started to become a standard when the most recent release of Safari (Mac OS X 10.4.3) happened. nonetheless, I decided it needed to be fixed.
so I fixed it.

the file below contains the standard feed icon in a form usable by Safari, and instructions for installing it.
