The New Republic uses something like this in a cool way. As you scroll down the article, a progress bar on top shows how far you are through the article.

because the browser scrollbar doesn't work well enough?

What if there are 500 comments at the end of the article?

Because the browser scrollbar indicates where you are in the page, not your progress through an article.

while i mostly agree, it does make it clearer that it's your progress across an entire article: with just the scrollbar you never know if you'll be facing "page 2, 3" links at the bottom.

On touch screens it usually disappears?

[lojack]

because the browser scrollbar isn't necessarily present on a Mac.

please this is not cool at all. Seriously, why we need another scroll bar on top. Because they create cool ngprogress and you want to be creative with it ? Nice try but due to my point of view, this doesn't work.
