Marissa is slowly resuscitating the image of Yahoo from a company that creates products for old people to a company that creates beautifully designed software and services for anyone.
While today's news was dominated by the Tumblr acquisition, I think the change that impressed me most is the dramatic redesign of Flickr along with it's 1TB of free storage. Bold move.
The only thing that I would have done differently is staggered the announcements to get more air time with the press. Fortunately, Marissa is a smart cookie, she'll figure that out soon enough.
