"We know what Twitter is, but where are all the tweets coming from? For answers, look no further than the one million tweet map.\nPowered through Maptimize, the Twitter map updates every time a tweet is sent. Every time 20 new tweets come in, 20 of the oldest tweets are removed.\nThe global map updates geotagged tweets through Twitter's API. The data can be viewed as a heat map or cluster and you can narrow the timeframe for when tweets were sent. See the video above for more information. \n\n"^^<http://www.w3.org/2001/XMLSchema#string>
