I've seen the word "teach" used to talk about setting up or programming a computer on many occasions before. It's completely appropriate. I can see why you'd be disappointed but that's not a reason to complain.
But, because of Siri's architecture, telling a forum of hackers that you've "taught it" to do something is a wildly different thing.
Hackers click that headline because they're interested in the possibility space where you can integrate arbitrary third party apps.
And when they discover that your headline is a semantic game --that the implicit promise of the headline is a lie-- I don't know how you could expect anything other than complaints.
But then I thought about it, and isn't this also an example of a hack in it's purest sense?
When I clicked on the link I realized it has not much to do with Siri and is just about synching other iPhone apps.
Last time I checked, there was nothing sticking up my ass, but I do come to HN because it is different from Lifehacker, BusinessInsider or HuffPo. Nevertheless I do have to admit that it is a brilliant marketing move. They even started a heated discussion on HN :-)
So to extend my comment from a hacker perspective I felt tricked.
From the perspective of an online marketer I have to admit it is a brilliant move.
> the have taught Siri nothing.
Not that having some jackass (me) be the arbiter of what's a nice way to say things is any improvement either, but I'm just saying.
