Yahoo is going away just like myspace! Without an ever changing product offering they will eventually be comoditized and loose their utility and value...already I feel like yahoo is kinda spammy. If a tech company doesn't innovate it dies.
They are causing nix what i ever seen of last few years. they block there work.Yahoo is even democratic and is one of the better contender of Google,Yahoo is still mending day by day so yahoo is even there.
There has been no additional feature being developed in Yahoo. It remains the same ever changing product which is losing its utility and overall significance.
