Ursula K. Le Guin in Words Are My Matter:

Present-tense narration is now taken for granted by many by many fiction readers because everything they read, from internet news to texting, is in the present tense, but at this great length it can be hard going. Past-tense narration easily implies previous times and extends into the vast misty reaches of the subjunctive, the conditional, the future; but the pretense of a continuous eyewitness account admits little relativity of times, little connection between events. The present tense is a narrow-beam flashlight in the dark, limiting the view to the next step — now, now, now. No past, no future. The world of the infant, of the animal, perhaps of the immortal.

I don’t at all mind present tense, but she does have a point.
