For those out there that use OS X 10.4, Safari 2.0 and it new RSS feed abilities, I discovered something which I had previously overlooked. If you have a number of “feeds” in your RSS folder, you can control-click and select “View All RSS Articles”. This will give you an grouped version in one page – sortable by any of the regular means. Very handy for first thing in the AM when you want to quickly browse all updates.
