Oh, you thought Google might take a break from snapping up startups this summer? Guess again. The search giant just acquired an awfully neat messaging app called Emu, which worked by injecting a little contextual intelligence into your conversations. Agonizing over tonight's dinner plans? Emu would surface its Yelp rating right within the stream of messages. Asking a friend if they wanted to see a movie on Friday? You'd be treated to a list of movies playing around you, and you could order tickets from there. Mentioning a day or date would also yield a tiny glimpse at your calendar so you could make sure you were actually free.
