Maybe it's been fixed, maybe it was my browser, maybe it was a heisenbug, but when I wrote my comment I clicked on the "wrote in a blog post" several times, and each time got a "Bad URL" message. I've just tried again, and this time it's sent me here:

http://googleblog.blogspot.com/2011/02/finding-more-high-qua...

which I assume is what was intended.

Fairy Nuff.

My real point is that the blog post lunk to here offers nothing extra to the original from Google, and to quote http://ycombinator.com/newsguidelines.html

    In Submissions 

    ...

    Please submit the original source. If a blog post
    reports on something they found on another site,
    submit the latter. 

I could be wrong, but this submission just looks like blog spam. Can you elaborate on what you think the submission adds over the original from Google?
