Dear Aoir: I first spotted this: http://www.text.it/mediacentre/default.asp?intPageId=847 interesting report on the Smart Mobs blog, and thought it was relevent to the list and might be helpful to someone's research. Here is a small snipet, "July 2005 marks another major text messaging milestone. Just as we spend 100 billion annually on food, there are 100 billion neurons in the average human brain and 100 billion stars make up the Milky Way Galaxy, we have now sent more than 100 billion text messages in the UK." Sincerely, Alla Genkina
