Mark Cuban's blog is quickly becoming one of my favorites.  He recently talked about how he got his money (part 1,part 2) and in his most recent entry, he calls out The Don to have a corporate meetup at Whitecastle.  I think Mark should hire me to do a reality blog on his life.  I'll just follow him around with a camera so when other famous people try to schmooz him and he calls them on it, he can back it up with video footage.
