There's so much to Google that it's easy to miss minor tweaks and major new offerings alike. Pay a regular visit to the Google "More, more, more" page (http://www.google.com/options). Stay on top of all things Google by reading or subscribing to the Google blogs, unofficial (http://google.blogspace.com) and official (http://www.google.com/googleblog).
