"Microsoft announced this week that Skype calling had arrived on Amazon's Echo"
Ah, so THATS why Cortana unexpectedly started messaging me in Skype for OSX the other day. I've told her to sod off and leave me alone, but I now have the nagging feeling that she's listening in to my messaging conversations.
You can imagine old Clippy - "It looks like you're trying to have a private conversation. Would you like help with that?"
