It’s becoming the most popular verb tense in fiction writing, and this article by Alexander Chee at Lithub.com defends it:
As a part time professional ‘creative writing tutor’, I can say I only ever teach the present tense as one tool among many. I do not urge it on my ‘sensitive and artistic storytellers’, or any of the insensitive ones either. I teach students that verbs are the way they create a relationship for the reader to time, and function a little like the way a horizon line might in a picture. As for using it to dodge the ‘politically dodgy’, well, I can’t imagine teaching anyone that way with a straight face—and so that strikes me as something of a straw man. Or, woman, perhaps.
