I personally don't like what they've been doing to their web portals (massive graphics, tabloid-style coverage, etc.) but that stuff isn't that important in the long run. They've been doing a lot of right things in mobile with a great weather app and news digest app that I use daily and have been reviewed very well by users. If you told me two years ago I would be spending time with Yahoo-powered apps on my phone multiple times I day I would have laughed.
