Over all, Yahoo remains much the same business it was three years ago. It is a far-flung collection of news, entertainment and communications destinations supported by ads. Ms. Mayer was hired to build something novel. Instead, at best, she appears to be building a better Yahoo — with debatable results.

We all know Yahoo needs to do SOMETHING to shake things up. The debatable question is WHAT? Everybody is quick to point out that Mayer isn’t doing anything… but nobody seems to have a solution.
