Woon and I made Twitter notebook, to help you to never forget to tweet and at the right time! We looked at Twitter data to see when people tweet the most, so you make sure you do to.
Data is (what we could find) from Jan 2007 to November 2009, showing total number of tweets posted per hour. It is categorized monthly with an-hourly average. Empty space is for you to note down when you are not tweeting.
