In May, Yahoo made its flashiest purchase to date under Mayer's guidance, buying Tumblr for $1.1 billion.

Promising "not to screw it up," the companies said Tumblr would remain a separate entity with the same "irreverence, wit, and commitment to empower creators." Founder David Karp stayed on in his role as CEO of Tumblr.

More recently, Yahoo acquired Xobni, a self-described "smart address book" with products for Microsoft Outlook and Gmail. The idea behind Xobni is to organize data -- email, text message, and phone call contacts -- so that your head doesn't explode from info overload after you log on.

Where will Mayer take Yahoo next? Given the breathless pace of acquisitions in the past year, the company has brought on board a lot of new talent. Now the question is whether the payoff will justify the price in Year 2 -- and beyond.
