The key innovation is the possibility to search in real time. “What’s happening right know?” became the main question.
Now, if you’ll choose “Latest results” or select “Latest” from the search options menu, you’ll obtain not only links to sites, but also see updates from Twitter, Facebook, MySpace, FriendFeed, Jaiku and others (video).
Also, Google adds “hot topics” to its “Google Trends”. They describe the most common topics people are publishing to the web in real-time.
Google says, the new features will be rolling out in the next few days and will be available globally in English.
