Jay-Z tweeted with fans for hours and hours.

Date: July 8

Like Rakim, Jay-Z has always understood the power of mystery. In the late '90s and early 2000s, he managed to drop five hit albums without revealing very much about his personal thoughts and feelings. (That all changed with The Blueprint). Even today, at a time when rap fans have known Jay for so long they feel perfectly comfortable referring to him as "Jay," despite the fact that are a million other rappers, and a billion other people, whose names begin with "J." Because, really, there's only one Jay. And yet, still, sometimes it feels like we don't know him at all. He's a cold fish. A king on a throne in a castle far away from where his subjects live. 

So weeks ago, when Jay went on Twitter to announce the "#newrules" that would accompany the release of Magna Carta Holy Grail he signed off by saying he wouldn't tweet again until 2014. We believed him. Jay never seemed to care much about Twitter anyway. So it was a real surprise on Monday when he logged on again and answered questions from his followers for most of the afternoon. He later told The Breakfast Club that it was like weed—he liked it so much he had to lay off it. But honestly, we kinda liked it better when we didn't know whether or not Jay even ate cereal at all. — Insanul Ahmed
