Yahoo is now allowing My Yahoo users to test out the new My Yahoo layout. Yahoo! lists the new features to be found at the new My Yahoo here. Jeremy Zawodny has some great information on this in his entry named New My Yahoo Beta, Featuring RSS and Atom. Anyway, I was smart enough to compare the old with the new before switching directly to the new design. Here are my first impressions of the new my yahoo design.
(1) Much more screen real estate. I was able to see two more RSS feeds I subscribed to with the new design. Reduces all the scrolling I do daily, I subscribe to tons of RSS feeds, so it helps.
(2) Search at the top but more features. Instead of a simple, Yahoo! Search box, there is the full Yahoo Search box that allows you to search Web, Images, Yellow Pages, News, and Products.
(3) Compact Design; this adds more room for more stock quotes - which I faded out from you below. More, more content. Good stuff.
I did not get into all the features yet, but it looks like a nice improvement so far.
Below are two screen shots of the My Yahoo pages, old and new.
