It is hard to say anything positive about Yahoo since Marissa Mayer took over the helm.
Useful services (e.g. Pipes) have either been eliminated or are just languishing (e.g. Mail). Today Yahoo Mail is down again. Alibaba's stake hasn't turned out to be the savior it was once deemed.
At this point the stakeholders are surely kicking themselves for not taking Microsoft's buyout offer back in 2008.
The future isn't looking too bright for this once thriving vanguard of the Web. Perhaps it is time for new leadership.
