Twitter Weather Map
Everyone loves twittering on about the weather. Wouldn't it be great to have a map of all those conversations? It may be small talk but this is one big idea from Walter Rafelsberger.
Walter's map fetches messages from Twitter which contain words about the weather. A KML file is then rendered and displayed on a Google Map. The map is then updated every hour with the latest weather discussions on Twitter.
Currently Austria, France, Germany, Spain, Switzerland, United Kingdom and the United States each get their own dedicated weather map. You can even add the map to iGoogle or Netvibes.
Walter says this is "just a simple example to illustrate the hidden power and possible emergence that lies within social media, presence services and live streams." He even says he produced the map in just three hours.
