It actually frustrates me that Siri doesn't give a hoot whether you thank her.
I want to thank her a) because it feels natural and b) to tell her that she's actually got something right. She's usually less use than an ice kettle so I want us both to get a kick out of it when she's not.
It could actually have function value as it could trigger some positiveness in a bayesian filter, subsequently increasing results accuracy. I let you be creative about the negative sentences.
Perhaps they'll add a thanks-awareness feature that will eavesdrop on your online conversations and thank you next time yyou're using it - "oh BTW, thanks for mentioning me to your friends on your blog" ... or y'know, maybe not.
