Ok, it sounds like you took it in the wrong way. I was not impugning your pictures, which are very good. Nor am I saying you shouldn't got to touristy places. They are usually touristy because they are worth seeing. I just wanted to comment on how different the places are that we go to in our daily life versus the places we go to when we travel.
For example, I now live in Iceland and when I was first visiting here, I of course went to the big tourist places like the Blue Lagoon, Jokulsarlon and Thingvellir. Now that I live here, I tend to go to different areas. They are not better or worse, just different.
The comment about ground zero is more personal for me and I am not saying others shouldn't go there. My father was there for the first trade center bombing and in a plane to DC the morning of 9/11 (luckily he was fine both times). My aunt had appointments in WTC I from 10:30 am until 5pm on 9/11 and the only reason she was not there is because she had a breakfast meeting uptown. My sister lived less than 2 miles away from WTC at the time as well and was trapped in the city when it happened, so it just hit pretty close to home for me. That's why I am not interested in going there...like I said, I have no problem with others going there.
Anyway, I hope you enjoyed New York it has so much to offer! Here is a photo from my current, less populated neighborhood.
Actually, I think the neighborhood of Brooklyn that I live in probably has more people than all of Iceland...seriously.
