Yesterday Microsoft announced to use Mozilla's RSS feed logo in the coming Microsoft Internet Explorer 7. This in my opinion is a great step towards usability and the recognition of de facto web standards. Hats off to Microsoft in this affair. I think this shows class and respect to the competitors on the browser market.
On my personal Blogccassion blog I decided to follow this example and changed the text-based XML logo ( ) I used before against the "official" RSS logo for making the web 16x16 pixels more consistent.
