Another Google item - this time the release of Google Instant. The search algorithm is always trying to give you the best result for your query, but this takes it one step further. As you type your search request, the google.com page returns updated, instant results, changing with each letter you type. It's quite likely that the result you are seeking will be shown on the page well before you finish typing the search.
This is a step beyond Google Suggest, which would offer you different search query options as you typed. This time, you are actually seeing results. And if it's too distracting, you can turn it off.
I like the way this works. It shortens up search time and gets you what you want to know. Quite helpful.
