Yahoo doesn't know the Innovation and talent of innovators this is the real reason why always is jumping from an owner to the arms of another owner selling the customers identification and data , since 1988 am using and working with yahoo I can say that might I know yahoo more better than lots of new arrived engineers as you call them but I never seen yahoo as a promoter and locomotor of the innovation always waiting Microsoft and Google and others to see what is new and what thinks the people for doing the same ,sorry but you are not really competitor and what you had brought is already seen on other e mail server company , your internal functions have still the same problems that 10 years ago without any changes every time you just change the background colours the font and global appearances but functionality is exactly the same obsolete machine, employ and pay better the IT designers also listen the customers , who make you living are customers even those non premium customers
Sincere regards
