My favorite comment from the post: "And by the way – how is this app strategic for you guys and Reader is not? A little clarity would certainly be appreciated." I too would love to know what Google is thinking here.
Combine that with what Google already knows (that I leave work at 5 and drive within half a mile of a grocery store), think about the intelligence they could bring to my Todo list.
(I know lots of people aren't going to like the privacy implications, my comment isn't meant to apologize or touch on that aspect)
