safari rss is nice because it shows a very usable way how different websites become unified behind one interface. an interesting co-existence of pretty designed eye-candy (ie. the original website which might violate usability and accessiblity standards) and the pure essence as easy accessible information.

safari rss is ugly because it's impossible to display the original xml source of an rss feed, eg. one which contains an xslt stylesheet. there's currently no switch, no hint, no setting (except a total turning off of rss features in the debug menu which is not visible by default).
