The folks at Google continue to crank out amazing products, and assure that I visit their domain about a million times a week. In addition to the best general-breadth search engine, they now have a 20-year archive of Usenet, and have put together a timeline of first-mentions (e.g., first mention Microsoft, first thread about AIDS, first thread about the Challenger disaster, first mention of The Simpsons, and even the first mention of Britney Spears), a search engine that’s specific to mail-order catalogs, and a search engine that’s specific to U.S. Government sites.
Really, Google is light-years ahead of its competitors; it’s a wonder people continue to use other search engines.
