Nas is doing an AMA at reddit http://www.reddit.com/r/Music/comments/233t3x/i_am_nas_amaa/
He was asked about ghost writing (it's the top question currently)
"How did you end up (allegedly) ghostwriting for Will Smith?
Edit: The song getting jiggy wit it."
"Alright, let's clear this up once and for all.
I hung out with Will in the studio. And watched him write it. It was a fun studio session, and I said a line or two or three to him. It wasn't that serious. Will Smith wrote that song.
But seriously, I watched him have fun making that record on his own, and Will is a true MC."
Well, I'm extremely excited that insurance companies can't drop me because of pre-existing conditions. I'm also very thankful that there's no more lifetime cap on what my insurance can pay. I think it's great that they're increasing the amount of aid for health insurance for low-income people. And the coverage for kids up to 26 is good.
The stimulus plan was a huge deal. Many, many economists argued that with out that the US would have sunk into a depression.
Obama's endorsed same sex marriage and appointed many gay officials, which is a pretty big deal (though more work needs to be done).
Ended the policy of torturing people.
Proposed and signed the Dodd-Frank Act, which while it's pretty watered down, at least tries to prevent another financial collapse.
Followed through with pulling troops out Iraq.
During his tenure and with at least some help from the US, Gaddafi is dead, there was the Arab Spring, and Osama bin Laden is dead. All of that with out launching a major invasion.
