Change is NOT bad when it IMPROVES things. Change IS bad when it makes something CONSIDERABLY WORSE!
I'm sorry, but this new UI for MyYaoo! is absolutely horrible. I can appreciate UI overhauls and redesigns, specifically when they are done to improve the user experience or make users more productive/efficient. What you have done here with MyYahoo!'s layout is an incredible step BACK in both departments. It is NOTa better user experience and it does NOT make me more productive.
With the old layout, I had 12 content "buckets" across a 2 column layout that I could VERY quickly scan to determine which stories/links were worth drilling into. With this new layout (and I've tried the 2, 3 and 4 column layout), it will likely take 15-20x as long to scan the same amount of content. It's simply distracting and a graphical wasteland of colors, pictures, links, etc. I cannot believe that this UI was actually field tested with actual users of MyYahoo! and was favored. Quite frankly, this is enough for me to go looking for a new "MyYahoo!" like alternative...and I've been using this service since the late 90's believe it or not. Each UI redesign in the past I've appreciated and had no issues with. This one though takes the cake in terms of taking 10 steps back solely in the name of "change."
