Your post is just not true. There are writers, artists, actors, etc who have been discovered through Twitter or have used it to significantly broaden their audience. @sosadtoday and Mira Gonzalez are two writers off her top of my head who basically built their careers on Twitter. And this isn't even getting into the "weird Twitter" phenomenon. Point being, people do read what you say and it's possible to get a lot of exposure. Maybe you're just not tweeting anything interesting.
