FYI Now the subject lines and links of all posts to this green-travel yahoogroup are mirrored to Twitter at
http://twitter.com/green_travel_gp [According to Wikipedia, Twitter itself estimates 25 million users by the end of 2009.] = = = Note I maintain a semantic green travel input feed into Twitter at http://twitter.com/greentravel1 I operate a semantic green travel output feed out of Twitter at http://twitter.com/greentravelbot Both these input and output feeds are controlled by my proprietary green travel taxonomy (faceted-classification database). Basically, the input feeds green travel news into Twitter, and the output feeds green travel commentary out of Twitter. The combined feeds @greentravel1 and @greentravelbot are archived and available on Friendfeed at http://friendfeed.com/greentravel1
