It's my understanding that the current orange RSS icon is not specified by any organization – it's consistent because of consensus across client authors.
If one of those organizations were to change their icon (like Google in their feed reader), it wouldn't be a uniform thing – each of the other client authors (Mozilla, Microsoft, Opera, etc) would then choose whether to follow suit or not. |
Ahhh, thanks for the information. Came across this in Google Base. |
