It looks like he's not having fun up on stage anymore...like, he's being forced to perform or something.
Just watch this video and compare it to his performances of today (which are not in any way bad performances...I'm just talking about him having fun)

While performing there, he looks into the crowd with crazy faces, shakes his head in different ways, look back at Proof and shit, takes weird steps that change with the rhythm of each song, rotates his arms/hands in crazy ways, and is just making a ton of eye contact with the fans..now, he seems to have "no emotion whatsoever so" lol...always got that same expression on his face...he's just...not having fun anymore (from what I see). Simple as that.
BTW, I am NOT saying his performances now are bad...he has a TON of energy..I saw him live last September 2010, first row, and it was the greatest day of my life. One of the best performances I have ever seen. This thread is just strictly about him having fun now.
Thoughts?
