    That's awesome! Might be worth adding in another class of keywords for the pending Hurricane Irene... it's been a hectic week for the east coast!

    Yes, I should definitely keep an eye on that too, although the pattern will be different because there is so much advance knowledge with a hurricane.

    You could also track the waves of Tweets radiating out from Cupertino yesterday after the Steve Jobs announcement :)

    Do you think there is really a geographic pattern to news dispersal like that? Maybe there is, though, and I shouldn't rule it out without looking.

    Just checked, and I really do think news disperses basically instantaneously. The only interesting thing is that apparently nobody says "Steve" or "Jobs" in reference to anything other than Steve Jobs anywhere between 2750 and 5000 miles, or more than 8000 miles, from Cupertino.

    Heh, thanks for the quick check! Do you think it's feasible to reverse engineer it- to search on terms that explode suddenly, and then see if they have any geographic pattern? It really may just be things like earthquakes, though.

    It certainly seems like it ought to be possible... I'll have to look into it. (I wonder if Twitter already does that for their trending topics.)

    You could try it for something that started local and got big, like Tweets containing BART & Anonymous or BART & cell phone

    Very cool, could be some interesting other things to play with using this idea. Like Octoferret's idea above!

    I'm thinking a 24/7 TweetMap stream.

    If you want to see them in real time on a map, Frog Design's A World of Tweets has that. The problem with real time is that it is pretty slow -- there are only about 15 geotagged tweets per second on the average for the whole world.

    Innovations like this should be rewarded. Great job! Unfortunately it looks like New York is falling into the Atlantic Ocean :) :( :/

    Oh, is it not quite lined up right with the base map? I thought I had it all adjusted. Or you mean in real life?

    Great work! I saw it first in the Adobe museum of digital media. Wonder how many times was this visualization tweeted?

  19. Eric Fischer 31 months ago | reply

    Thanks! It is hard to tell from the stats. There were 481 hits from t.co (the Twitter URL shortener) on the peak day, but many more "unknown source" views that could well have been from Twitter too.
