I’m not really sure how useful it is, but it certainly is interesting to see 11,000 tweets plotted over 24 hours – all relating to a “good morning” tweet. The colour coding shows what the time the tweet was sent (green is “early” while red is “late”).

This data visualisation reinforces the preconceptions of have of the USA – people around NYC get up and go (heavily green areas) while people over on the LA/San Fran side of things are a bit more laid back (a lot of red).
