Google NGrams lets you see how usage of certain words in books has changed over time, from years 1500 – 2008.
See how to pronounce huge numbers by searching for the number and then typing =english, eg 1234567890=english produces “one billion two hundred thirty-four million five hundred sixty-seven thousand eight hundred ninety”
Google Trends lets you see what the top searches are right now:
You can also enter a search into Google Trends to see how a search term has trended over time: http://www.google.com/trends/explore#q=awesome
