Everybody has their own ideas about what they should build at Ground Zero. I remember thinking a tall slim tower taller than the older ones but perhaps more a monument than an actual building that holds people. I don't know; maybe the idea was a cop-out. At any rate, what they're doing looks good, though I don't know all the details.
Update: I realize the link is wrong. I will fix it as soon as I get a chance.
Ok, I fixed it.
