Whether I spot my own typing errors depends on whether I'm not wearing my reading specs (lethal), using my iPhone (severe), both those at once (which generally means I'm posting whilst still in bed, leaning up on one elbow), or using my iPad mini (mild to moderate). It's rarely worth picking anyone up for their little peccadillos, unless, of course, they're having a go at me for mine. Then it can become open season, as Nigel will tell you... ;-)
