Fish: A Tap Essay is a new app created by author Robin Sloan. It's not a game -- it's an essay. Words. Thoughts. Robin puts a few words on each screen, maybe a sentence or so, and then you tap to move on to the next set of words, the next thought Robin wants you to consider. Robin had noticed that there were plenty of chances to "like," or "plus 1," or "star" or "fave" things on the web on social media. And it's easy to pass those things you like on to friends, but the like never turns into love. Also, the city where you are most likely to lose your cell phone.
