Judging from what is rolling off my RSS feed, Google Instant seems to be the news story of the week. This short video compares searching with Google as normal versus Google Instant:
Those who go to the classic Google page for their searches would experience Google Instant and figure out what is happening with no explanation. People like me who have an iGoogle homepage and search from there do not experience this new development.
So, if you haven’t been to the Google classic page in the last few days, take a test drive and see what you think.
