Several people are reporting seeing Google automatically take them to the search results page from the Google home page, as they type a search query. Imagine you are on Google.com and you begin typing a search query. Then all of a sudden, as you type, Google flashes the page into a Google search results. Even before you press the enter key or hit the "Google Search" button, you are taken to the search results. Sometimes, even before you complete your full search query.
There are people reporting this at Google Blogoscoped Forums and WebmasterWorld. In fact, Websonic.nl posted a video of this in action:
Earlier we saw reports of Google updating the search results as you type but that was only once you were on the search results page. Now, Google seems to be dynamically showing you search results from the Google home page. Big difference here.
I suspect this will indeed be part of the big Google search announcement today.

Update: I was right, this is the big announcement, more details at the Google Blog.

Barry - I think this will probably have a positive impact on Google revenues (by pre-empting some longer tailed searches) and a negative impact on advertiser expenses. The latter will likely happen as there will be an increase in clicks and impressions for more expensive "suggested" or auto-results terms. Ergo, more ads will be coming up against 2,3,4 word phrases as opposed to against the original long-tail phrase the searcher might have typed in.

Sigh. Another "feature". I want the results from MY search terms. My COMPLETE set of search terms. Otherwise, your "search engine" is USELESS.

It's really nothing new, Leapfish has been populating/changing the search results like this for a while now.

I haven't seen it yet but it looks pretty cool. And it looks like it doesn't interfere with a user's typing, so if you want to complete typing in a phrase you can.

Quite distracting while one is in the process of typing a search

It called Google Instant, when I clicked on the more info link it said this: "Google Instant is rolling out over several days to users signed in to a Google Account. Check back soon if you are signed in and do not see it yet."

This is a cool thing for me. I have experienced something like this and I think this is very useful, especially when we are looking for a certain "search" and google scrolls down that we will find more suitable with our search. This is a clear suggestion of searches. Nice one from google.

I like the way the video @ Google Blog ends with an old guy saying "look at that. I like that."
