According to a recent study ("Who Says What to Whom on Twitter"), 20,000 elite users -- celebrities, bloggers, and media outlets -- comprising less than 0.05% of the user population, attract almost 50% of all attention within Twitter. That explains why millions will be familiar with this representative tweet from Meghan McCain, the 27-year-old daughter of Sen. John McCain: "OHHH MY GOD—A BIG JIANT ­SPIDER JUST CRAWLED ON MY ­PILLOW!!!!!! ARGHHHH OMG OMG OMG EWWWW OMG!!!!!!!!!!!" No, the apocalypse is not nigh. It just feels like it is.
