So for anyone wanting to go back to orange and yellow post icons, removing the left hand column would be easy, but were there some major changes done to remove the differentiation of read and unread icon colours?
I don't really buy the bandwidth argument Scream mentioned earlier, unless it's a text based web site. Look at the file sizes, they are tiny, a little over 100 bytes. You still have to download the yellow icons so the extra set would take up 2-3kb. Probably a quarter of the size of their logo. And they're cached for future references.
