I'm only 17, and I'm a little ashamed to admit that I'm somewhat of a 'binge reader', and before a couple of years ago, I went a long time without reading at all. I regret not taking the time to read much, and my vocabulary is none too dazzling. At the moment, my reader is basically my vocab teacher. A couple of my most recent ones are 'craven' and 'vehement'. Aside from leaning new words, it's also nice to definitively have a rarely-used word defined, and then used in the context of the story. All in all, it's a good help to someone who's vocabulary isn't particularly developed
