Twitter would be another great addition. I think Apple would do better to start thinking of promoting best-of-breed services even when they allow others from outside the "walled garden." Steve Jobs pursued buying Dropbox but would have made it Apple-only. It shouldn't insist on this. Same goes with something like WhatsApp in the messaging space. There was yet another iMessage failure yesterday. This can't happen and it would be more powerful to have an open Messaging platform like WhatsApp than insisting on keeping iMessage as a closed system. Twitter would also have to remain "open" to non-iOS users. The bottom line is that Yahoo! can be extremely helpful to Apple in charting out these kinds of new services. For those who like to put down Yahoo! as a non-factor in web services, I'd say: (A) You're still bashing Yahoo! as though it was a $14 stock instead of a $24 one. (B) You're bashing flies in the face of raw user numbers to Yahoo!. (C) Finance, Sports and News are monsters for Yahoo!. (D) Marissa Mayer is overseeing a rehaul of all Yahoo! properties for mobile and Apple can benefit from this rehaul. (E) If not Yahoo!, who else is Apple going to partner with to help with this new web services area? Google? Facebook? Microsoft? Exactly. Forget Blue Ocean or whatever else is the strategy fad of the day in Silicon Valley: Yahoo!'s strategy will be a mobile Switzerland one for the foreseeable future.
