Google Suggest
(Via O'Reilly Developer Weblogs)
The latest beta offering from Google gives you word completion in the search input box. As you type, a popup menu appears with suggested words to search for. It works for phrases, too. It seems to build the list of suggestions from actual text found on the web; it will present you with common typos to complete your words. For example, typing "google su" will eventually get you to "google suggest", but the first completion is not flattering to Google.
Patrick Gaskill has already created Suggested Google Alphabet, a web application that automatically checks and displays the most popular Google Suggest keyword for each letter of the alphabet.
