Google search was an amazing improvement when I found it in 2000, but sometimes I wonder if the post-2005 improvements of search results is nothing but a reflection of human progress digitizing data. There is more data online, and better organized than before. That improves google's results regardless of algorithmic strength. For any search where the first result is Wikipeida, the following results don't have to be any good, and there are plenty of terms where the next 20 results are just domains with lots of in-links hosting glossary and dictionary definitions. Tech was the first area to conduct large amounts of our work online and in the public's eye. As a result, almost all our meaningful literature, documentation, q&a (was mailing list archives, now is just stackoverflow) and "here's how I solved X" blog posts are available for google to scoop up.
