Google started its full realtime search effort, but it is still to be determined how useful it would be for the general public. It will be handy for bloggers, techies, analysist, journalist to measure the current thoughts and trends, but still not sure how popular the service would be.
You could refine your search results and it is quite handy with its geographic refinements to find updates and news near you, or in a region you specify. Also it has conversations view, making it easy to follow a discussion on the real-time web.
You can add updates content to Google Alerts, making it easy to stay informed about a topic of your choosing.
