Personally, I don't want them to be too different. I like the way the world financial center looks, with all the towers very similar. Although I do agree with what you say. The WFC is a perfect example of this. You can't admire each of the buildings for their own because they look so alike. But I would prefer at least that they all have the same facade so it won't look like a mess. It'd be nice if they all had their own unique qualities(like the roofs on WFC) but still be similar in appearence(like the facades of WFC). This way you can at least tell they are part of the same complex. I also am glad that the tower will be one tower, instead of a spire connected to a tower. I agree that it'll be much safer. I also think it'll make it look much better. It will make the REAL office building seem taller. Since they are one building now, there can be no argument over what really is the Freedom Tower and what its real height is. Also, hearing about this wind power, I'm getting very excited. I hope they can make it work.
