A post by seo-ireleand at our forums named New look Yahoo Directory listings notifies us of a slight change to the UI of the Yahoo! Directory. Take a look at the Y! SEO Directory and see how it is incredibly spaced out, between results. I have attached a small screen capture and a larger screen capture to document it. I do not have a screen capture of the page before hand.
So it makes me wonder if it is really different. But I really thing there was a change to, at least, the spacing in the directory pages.
