I'm sure I'm in the minority but I don't consider ping a social network (nor do I Twitter, honestly). And that's just me. Twitter is so much more communication focused in my book where things like FB anf G+ have been more frivolous.

I never thought of Siri as search. To me it was more about interfacing with your device.

Did Siri flop?

yes it did. I tried Google Now the other day. It blew my mind. Google Now understands every single words I said (Asian accent); As for Siri, 50% is kinda optimistic.

Is that what determines a flop, though? Siri is definitely known, and added value to the iphone and the apple brand overall. While I use Google Now and think it is superior, I'm not sure if performance would be enough to label Siri as a flop.

Bing on the other hand, not so much.

Probably the differences are only noticeable for non-native English speakers like me only. It's way too good that it makes me feel Siri is such a failure.

Native speakers might not see a huge difference though.

I am a native English speaker and Siri constantly misunderstands me. Siri has become a punchline and certainly does not have the usual Apple Cool Factor.

It's probably still to early to tell. But I don't see how anyone can dispute that Google Now is basically what Siri tried to do, but significantly better. I'm yet to see Apple's response to that.
