It would appear that Google is working on the problem associated with real time search. Twitter currently has the market cornered on real time information gleaned from tweets. Back in October Google signed a deal with Twitter to index tweets and return them in the search results. Very soon we will see real-time results when performing certain searches in Google.
It will be interesting to see how this has an impact on user behaviour. Will Twitter become more relevant or less? Google also struck a deal with Facebook so we can expect to see more of that content appear in the Google index.
