Googles search now realtime as it integrates real times feed from twitter .
Type some thing which is doing great on twitter (trending topics ) and then you can live stearming from twitter displayed.

This real time integration of google is not limited to twitter alone . there is live streaming of updates from facebook ,myspace, etc, also yahoo answers and news articles ae streamed
This google has included real time to compete yahoo and bing who have already struck deals with social networking sites. what’s more this works on mobile phones too.

This means I tweet something and it is live the next second on google , but well they may not be relevant for all, But this is nice to get breaking news on google or instant reviews of latest movies all before google indexes pages !
So well if you want to show up on the front page of google use social media tools ! This really works well and is so easy . I actually saw some of my tweets live after some minutes of my posting or rather shall I say seconds!
