> Is there a URL in the top million ranked URLs you could MD5 hash collide?

This is answered in the article. No

"Q: Is it possible to make a file get an arbitrary MD2/MD4/MD5/MD6/SHA1/SHA2/SHA3, or the same hash as another file? A: No."

I'm not sure page ranking works that way.

But you could get people to share www.nytimes.com/2011/05/02/world/asia/osama-bin-laden-is-killed.html?garbage=blahblah and collision it with your site crappyproduct.com?rubbish=meh
