Google Real-Time Search Bookmarklet
ReadWrite Web has discovered a way to make a simple tweak to the URL that Google returns and get back real time results. However, as you can see from the images below, they still have a way to go. For example, a search for NFL surfaced 10 result. Meanwhile Twitter alone is seeing hundreds of tweets per minute, each of which has it's own permalinked page.
So even though it's not ready for prime time, the move is work watching. If you're interested in testing this out here's a bookmarklet you can use for as long as Google keeps this URL schema running. Just create a new bookmark with the following URL, click on it, enter your search and you will get back any results Google has uncovered in the last 10 minutes.
