Social network technology like Twitter and Facebook are reshaping our world. Revolutions like the one that happened in Tunisia could not have worked without it. The above link is a good news article bringing the attention of twitter and its use in this revolution.
My Two Cents: Over the last 5+ years social networks like Facebook and Twitter are technology tools that are changing the way we communicate worldwide. If you have read news stories from most news websites like CNN, MSNBC, or FOXNEWS they have facebook comments to most stories. I find myself reading the facebook responses, and after a few comments, I get a different feel about the news story with the social discussion verses one without. I can see where government propaganda that might of worked in the past to control the people doesn’t work today, without the use of force like we saw in Iran.
