The more you know, the less you wish you knew. Social media has enabled a level of embarrassing over-sharing and self-promotion from rappers who, in previous eras, were more content to keep their knowledge jewels on tape. And it made them more interesting for it. Rakim wasn't getting into Twitter beef with Big Daddy Kane, and Kool Moe Dee wasn't subtweeting LL Cool J. The mystery that surrounded your favorite rapper made their music all the more interesting and made you focus that much more on the lyrics. They were rappers, not performance artists. Today, a Riff Raff fan is more likely to quote his Twitter than his music. In hip-hop, less is more. It's just not the same watching Cormega livetweet a basketball game. Actually, on second thought, watching 'Mega livetweeting is one of the rare examples of this working out for the better.
