It's obvious that the author of this post didn't talk to any actual Googlers, and I would assume Facebookers (Facebookians? Facebookites?) as well. In fact, I do use my phone to find coffee as the coffee cart (which has better coffee than what's in the microkitchens) moves around every day. In fact, I happen to use my phone for finding coffee more than I did when I worked at a startup where I'd go to a brick and mortar coffee shop that was always in the same location every day. Not to mention that I also use it to hunt down cafes as well. Plus, there are plenty of short pithy updates on the internal Google+, location updates on Latitude, and take pictures of funny things we see to post on memegen.
To be completely honest, I found the whole tone of this article to be condescending. But most posts that bemoan some segment of the population as "not average people like the rest of us" are.
