@confluency Exactly. Search has become a disaster because the net is flooded with "information" published by SEO experts.
Most of the time now, when I read an "informative" article about some topic or item, about a quarter of the way through I realize it was written by some guy in India who has no expertise in the field, but assembled information from other sources. Those articles often go on for pages and pages, saying the same things over and over using different wordings. Often there are ten different presentations of the same material.
Check the next seemingly unrelated site and it has the same text as the previous site, just arranged in a different order, or is an exact duplicate including the grammatical errors and incorrect usages of terminology.
The first page of search turns up nothing but this "content mill" gibberish. I hope serious students aren't using this crap to learn from.
