They've pretty much lost the desktop search engine market. The mobile search is still petty nascent and lots of opportunities for innovation and a market leader. So I'd get on the forefront of mobile making it the thing to focus on possibly partnering up with a hardware device developer. Fork Android OS and make customizations to it tailored for Yahoo services. Invest in R&D for mobile search and bring something new and useful to the table that nobody else like Apple or Microsoft has to wow everyone and put them back on the map as an innovative company. ie. still lots of mobile browser inefficiencies that can be improved upon. Lastly make everything lean and mean, and focus.
