You have probably heard that the Library of Congress is to archive every single public tweet ever made. There are about 55 million tweets sent every day.
Google also revealed how it is going to make the Twitter archive searchable for users. Google unveiled a replay feature that lets users search tweets posted at any given point in time right down to the minute.
Anyone wanting to know what people tweeted about on say the Haiti earthquake or the Oscars can type into the Google search box, select "show options" on the result page and then click "updates". A timeline will appear above the results allowing you to zoom in on tweets by the hour or minute.
Google says, "We think this is pretty significant because up until now the discussion has been about what is happening now and with today's replay button people will be able to go back and see what people were actually talking about around big events."
Currently the replay feature will only cover the last two months of tweets. Google said later this year it hopes to cover the entire archive all the way back to March 2006.
