There is a sort of rating system, in the follower ratio. Each follower represents a "vote" for the value of that person's Twitter stream. It's not only the number but also the ratio. There are people who have 200,000 followers because they are following 200,000 people. This tells you their tweets are worthless. (And if you're following 200,000 people, you're not reading their tweets.)
