As a general rule we don't use Google search any longer, the results it returns are not as meaningful as those of other search engines. And now, well, I was told to try this search on the GOOG:

And as it turns out the scroll is far from infinite, after 100 or so hits it circles back to the top.
Leaving huge swaths of internet inaccessible via serendipitous search.
This has not shown up in other countries but for searches in the U.S.A. a whole bunch of sites just got disappeared.
